I just learned about this place... I found it kinda randomly and I'm not really planning on joining, but I don't have a problem with it either.
I've had some stuff rejected by epilogue, infact, I've never had anything accepted. I'm trying to just take it on the chin and see where I can improve and think of the whole thing as a learning experience.
But I do have to say that I agree with the inconsistancies. In fact, a few people I've talked to on epilogue (mostly people who've I've met elsewhere, and found out they have a gallery there) said they see it too. Ofcourse I won't name names because that's terribly rude and its not that artists fault.
But I think the solution shouldn't be that hard. The problem is that the mods are inconsistant... so they should have 3 mods vote on every piece submitted. That way, if 2 out of 3 think its good/bad/needs work.. then maybe things would be more consistant. One person might not have a good eye, but 3 people combined probably will. I know it's a lot of work, and they'd need more editors, but I think it would be worth getting more volunteers for.
Anyway, I don't know where the suggestion box is at epilogue, but maybe you guys could get the idea to someone important.
