Falcorian(talk) - I'll help with what I can. If you need me to transwiki, I'm more than happy to do so. But I'm done trying to rescue articles that Wiki doesn't want.
Rogue 9 Project copyeditor. Please contact me if you're unsure of spelling or grammar and I'll check for you.
Cam Two years of 40k, collect Tyranids (Hive Fleet Destructus) and Imperial Guard (12th Cadian Regiment), along with plans for Eldar and Necrons (under Necron Overlord Anethron the Darkener)
Nemesis646 (talk): I collect a mix of Imperial forces (largely Ultras and Guard) and know about the literature and special characters.
Protonk (talk) Guess I'll put my name here since I'm fiddling with your categories.
User:StormySan Been playing for over 10 years now, hope to be able to provide some good input.
User:Lemming42 I am very knowledgable about Warhammer 40k, despite only being in the hobby for 4 or 5 years. I collect Imperial Guard, and WHFB Lizardmen.
KillTheToy I've got pretty good knowlage of the fluff for Chaos and the Imperium. I'll probably focus on Chaos, though.
Heatedpete - I'm an editor on the Warhammer 40,000 wiki, as well as here, so if there is any need to help with some of the transwikied articles after they've been copied, I'll be happy to help. Over here, I'll mainly concentrate on the Space Marines and Chaos areas of the articles, as that's my hobby base.
Eralam - I would like to help make more dedicated, specific and truly comprehensive articles on the background of the game and descriptions of vehicles and biographies of special characters and such like! Please message me to help with Vehicles of the Imperium article creation! I am very knowledgeable about the history of the Imperium and the other factions, as well as their social atmospheres and actual in game tactics if that counts for anything (which I suspect will not)
Cypher7850 - As a gamer who has played a majority of the 40k games, I'd be glad to help edit the pages of W40k games.
