We are currently ranked in the neighborhood of 1400, with 11 of 30 members. (only 5 of us are currently active. the other 6 are family members, and if we should hit 30 members I can talk to them about removing them from the guild. For now, they aren’t really hurting anything so I figure they can stay.)
Last week the 5 of us fell just shy of hitting the 2500 Seal benchmark for the new Guild Key system, so we could use a few more people to throw trophies, gold, and seals into the pot.
No minimum, as long as the roster says you are contributing that is good enough for me.
Let me know if you are interested.
