If you are looking to focus solely on crafting and collecting items to decorate your house and have no interest at all in helping with PvP, go away....now.
Not to nitpick, and maybe it's just the wording, but is this really seems kind of negative. The email invitation said:
"Remember that we are gathered here to continue a quest to fulfill our gaming goals in a family environment catering to gamers of all styles, all genres and with every sort of gaming schedule imaginable. It is a guild environment that asks its leadership to inspire our membership, rather than require anything of them. One that chooses to promote through ability and merit, rather than statistics and elitism..."
Granted, it's a PvP game, and people should know that going in, but IMHO folks who aren't really all that interested in PvP but want to experience the game world and contribute to the guild through crafting for the guild shouldn't be made to feel they're unwelcome (especially after getting that invitation). And who knows, they might even get into PvP and have a real talent for it.
