My guild is recruiting again. We could use a few more good people. We're on the North America Lethon server, which is a medium-sized PvP server.
We raid (25-mans) 3 days a week: Wednesday, Sunday, Monday from 7-11pm Pacific Standard Time.
We have 4/5 Grand Crusader, and 5/9 Ulduar Hard Modes. We use DKP, with regular Auction-style bidding. We're reasonably competent, and expect people come prepared and use food and flasks.
Anyways, this sounds like a guild you'd be interested in, please check out our website. Or feel free to ask questions in comments to this thread.
