I'm new and not savy enough to know how to add to a wiki.  But I didn't see a link to the videos at this older site -  http://perpetuum.wikia.com/wiki/Category:Videos -  which were of great help to me and might be to others as well.

Thanks to all of you who put in the time on the site, it's certainly made a difference to my quality of game play.

Edit to add:  I know they were from the Beta era, but they still seem relevant. o/
