@Captain Redhorn is your man to talk to about connections on JC with imps. I think there's a guild that has quite a few old POTCO members called "Umbra" if it hasn't disbanded or anything since I was last on...
Yeah, as Solomon said, I am the guild leader of a small group of ex-potco players on JC impside called <Umbra>. We have about 10-15 active members, most coming from either the POTCO wikia or the former POTCO Players wikia. We pvp a lot and occasionally run operations and flashpoints. If you'd like more information, you can message me here or in game with the name K'ell. Hope to hear from you soon!
