thats one of the things i had had in mind making my little list before.

Of course, the general idea is hard work with only small benefits - and no one ever said to implement it asap - but some of its negative points can already be reversed just by putting up the right conditions.

Pros:

-> an inactive account that had subbed just once and comes back can spend masses of EP at once; same with those guys that ragequitted, tried to misuse gamemechanics, maybe even tried to destroy the game/community... if they had a years sub - they could come back anytime without any punishment;
players that had been loyal active players that began out the same time as them (maybe couldn't afford a year) put their everything into the game but because they couldn't immediately continue their sub for reasons whatsoever are "penalized" with less EP than the inactive account -> so why not reward them by giving them the chance to buy a little bit of their absence time back;

Problems:

1. EP buyable in general, EP extends over the time of your subscription;
   only already player that had a sub can buy back EP for a certain break time between their subs -> already gives the first two limitations: trials can't buy EP, EP-payback limited by unsubscribed days in between subscriptions

2. player leave game until a patch comes that fits them and buy back the lost EP of absent time;
   limit payback days to a maximum and also the unsubscribed time - for example: limit is set to 30 days EP-payback (my initial post), if you don't resubscribe within those thirty days no option to get a payback; why a maximum of thirty days? normally big game-changing patches come only every two months.

3. Problem that may result: "Oh, I just bought back the EP, resubbed for a month, vanish again, then buy it back again";
   minimum timespan where the account had been continuously subscribed (without a day/second break) to enable the option (had set it previously to 6 months because a normal player wouldn't count as new anymore then) - example: player has subscribed for 6 months, got his last paycheck two-three weeks too late, therfore wasn't able to resub immediately, then subbed again and bought back his lost time, next time possible would be only after additional 6 months of continuous subscription

4. "no risk whatsoever.." - others sub for a year unknowingly if the game runs until then;
   option only available if resub for more than just one month (like 3 or 6 months), evtly penalty because of the lower risk - why? to gain the possibility to pay for absence time the player has to take another risk before with subbing over a longer time;
   > still, of course the risk is lower than the player who paid for a year

5. Problem: less full-year codes bought?
   Who buys one year-subs and why? The main points of one year subs is the discount and the big resubbing stress less, isn't it?
   So topic price: buying back EP costs you something, at least for 30 days a full month without any discounts -> result: player has to pay more than for a years sub;
   topic stress: having a month break from the game, you won't only have to resub (buy/pay code, redeem it) but in addition to that also activate and buy the lost time back = double stress

Still remaining Cons: (sry, dunno a comeback to them )

• less risk

• how to code such a thing without backdoors that could lead to an EP-store and without destroying the fundamentals of the game?

+1

... still anyone could set himself as ceo with just spending a few days worth of EP - what if more than one person wants that position? (since there can be more agents deputy ceos too)
Would suggest an additional majority vote system if more than one agent nominates himself. Of course voting should then only be possible for active players. (If the corp is still running smoothly the vote system won't be necessary because only one will apply; if theres no unity u can still give your vote and if u don't like the results you can still leave the corp).

looked through your build just now, so here are my two cents, if there are any question don't hesitate to ask:

You only have a month of ep to spend on, so orientate on one path for that! You can work on the others later on.
At the moment you have too many of them (<< khanatos.agent).

• Research + Proto
  Research is only necessary if u want to prototype, but will have the most effect at extensionlvl 8 from the beginning. Prototyping gets you some bonuses but it's a moneysink, since u will mainly sell massproduced items. Dont think of producing  ammo with it, its not worth the materials.
  => only take that path if you have a second account to farm masses of kernels and/or if you are in a corp that already has some producers.

• Massproduction
  with producing you sell the items at market for income. For the beginning: to be able to buy the materials your mainincome will come from geoscanmissions (until you have enough money for a sequer) then transports. So 'Parallel Assignments'lvl3 (to take 4 missions at once) is a must have. Next step can be to RE ammo or standarditems and massproduce them for selling (doesn't need proto).
  extensions:

• Reverse Engineering (RE)
  is the necessary connection between proto and producer, but you wont really need more lines or more time at the beginning.
  => install the extensions if you have some EP left after some months

• Market
  necessary for sell- and buyorders or less tax, get 'basic marketing' lvl2-3 optional; but dont put too much EP in Finances, there will be enough profit even without it; you can raise it later on bit by bit.

Since you want to produce to sell I advice you the massproducing path. Kernelfarming for Research+Proto would only pay out with a second pure combat account (not Agent!). Even so later on you will need connections to get prototypes or CT's to sell higher.
All in all it would look like this with pure industry attributes (ICS):

• Basic Extensions: 26.943 EP
          "Advanced efficient mass production" : 1,
          "Basic efficient mass production" : 5,
          "Basic extensive mass production" : 4,
          "Basic parallel assignments" : 3,
          "Basic robotics" : 4,
          "Industrial robot control" : 4,
          "Intensive mass production" : 4,
          "Navigation" : 4

• Optional Extensions:
          "Basic marketing" : 3 = 398 EP,
          "Diplomacy" : 5 = 5.460 EP,
          "Navigation" : 7 = +3.135 EP
