Please forgive me if this is documented somewhere or if I'm just overlooking this, but I'm trying to join my friends and their guild, I found their guild, am on their site, can view their rosters, etc... but I don't see anywhere specifically to apply. A friend seemed to recall filling out a form rather than just posting something on the guild's public forums, but I dont see anything of the sort.

Is there something/somewhere specific i need to go to "apply"?

Please help.

Thanks!

Now that the game has started you need to make a character on the server your friends are on. An officer or the leader of the guild has the option through the game to invite you into the guild.

The applying to a guild was just for before the game started, now that it is launched you do the guild management from within the game.
