To help spread the word, it would be worth it to visit this link. It contains descriptions of old PlanetSide outfits, some of the pages link to their websites. If no link to their website is given, some of the outfits can be googled and their websites found that way. Many of the outfits have disbanded as well, but there is a good chunk of active forums and groups that can be reached. If I don't see posts on all these available forums leading up to April, I'll do it myself, but I'm too busy at the moment to dedicate time to this (college n' stuff).
