I belong to two guilds, one at the state level and another at the next county over from me. Both guilds are great, and I'm the retreat chairman at the state guild, as well as the sponsor & public relations chairman. I've really enjoyed both guilds, they are full of really fun people who make everyone feel welcome and wanted.
The guild in my county won't let me join because I'm a man, though. Boo to them! :evil: They regularly have about 70 members at each meeting, but have an "old guard" that will not allow change.
