I don't think I've ever heard of that guild. Frankly there are far too many guilds in the game. Most guilds claim to be casual and friendly. In reality they vary a lot, and you'll find jerks in every guild.
You might also go to our wiki, find Category:Guilds, and read some of those pages. But that will probably be very slow.
My advice is to join a guild, just to try it out. Stay for at least a week. After that, don't be afraid to leave for another guild. Also ask the guild masters questions if you want.
I have a lot to say about guilds, but most of it is hard to explain, so I'll stop there. Good luck.
So i've been looking at the guild forums, and I think my best bet would be Shadows Might. can you give me any feedback on this choice?
