For those visiting this group and wondering what's going on or attempting to join, please read this. The group was hacked, and in response to the hacker, DeviantArt wiped the group's front page and content and blocked further new members and submissions.
Given the fact that its founder hasn't been active on the website for some years now, it's likely that this group is effectively dead. Mourn it, damn the hacker for trashing it, and damn DeviantArt for their scorched earth policy.
