I just stumbled across this site last night, following the same link you did, no doubt. I don't know if I'll bother registering here or not so I'll just be anonymous, but identified, for now. I'm sure you'll recognise the username in the subject.
Now you more-or-less know me. Not on a personal level of course, but you've read my posts at RPGnet, and possibly at Epilogue. We've even spoken by PM in the past. I trust that you realize I'm a pretty reasonable person.
With that said, yes. I've seen some pretty nasty comments here, and some direct attacks which I think anyone will agree is rude.
But I read through this entire site since I got here, and the overall tone is pretty civil. To my eye, this site is more of a support group than a hate fest. And it is very true that much of the animosity here is stirred up by Epilogue fans coming in with the distinct intention to raise a stink.
It is also true that these people have a grievance. It's not so much that things rejected and found in the WIP forum couldn't use more work, or improvement. From what I know of you, I think you'd be one of the first to agree that anyone's work always has room for improvement, regardless of experience.
The point these people are trying to make is that the rejection level isn't consistant. It's not about crying that their work should have been approved because it's perfect. It's about work that is many times worse than some things struggling in the WIP forum, being routinely approved. The trend is readily visible in the daily list of new art. The inconsistancy of the work accepted has been getting progressively worse over the couple of years I've been an Epilogue member, and it wasn't what I'd call great when I got there.
Certainly this is an opinion, but it is the opinion of many, and they are entitled to it. Bringing this issue up with the powers-that-be at Epilogue does not work. I've tried myself. Any questioning of the system, or suggestions for improving the quality of the review process are met with dismissal at best. My own courteous (and single) inquiry met with more than a little hostility.
The situation didn't bother me a great deal, so I just stopped hanging around as much. I figured, it's their site, they can ruin it if they want to. Other people are more concerned and dismayed. They wanted a place where they could discuss such issues without censorship (which they cannot do at Epilogue). So they created this place.
Like any fledgling enterprise, it's getting off to a rocky start. But the tone is improving. You can see it in the progression of the threads, if you care to. This site is maturing, and as it does, it may have the potential to be a very good thing. From what I've read, that's what they have in mind. We'll just have to wait and see. But in the meantime, please try not to judge these folks too harshly, or to judge all of them for the rudeness of a very few.
