Are you selective with who joins the group? Since I applied two times for membership and I'm still not accepted. Is it because you accept members with only homoerotic artwork, and not those who just appreciate the same? If there are such rules, you should clearly state them in your group, we can't read minds you know.
Also, its highly rude and unprofessional for you not to respond to any of the questions/complaints in the group for months time.
