I doubt if anyone will burn you, I personally do not post in the art galllery but like you I wouldn't mine helpinig out on a part time basis and I have and do have mod experience a total of about 5 years worth. I offered in another thread but got no reply so guess they don't think much of my offer. lol I'm pretty used to V Bulletin.
Yet am still willing to help out the idea of having 2 galleries may just stop people from uploading something that has no class to it or was accomplised with no effort put into it. I also have along with my husband our own art community, none of which would interfer with spending a few hours a day here helping out where ever needed. That is pretty much up to Admin, yet it doesn't take much to know quality vs quanity. I also think this should not be specifically for the art galleries it could also do justice to this site to also limit some unwanted items uploaded in all area's.
At least you openly made the offer that has to count for something positive.
I'll make the offer also, the main thing is to have moderators that are willing to help out Admin obviously they can not do it all alone. I'm not a great artist but like you I do know the difference. So its up to Admin now. I work mainly in Poser, Bryce and Vue Infinity,Terragen and a few other programs.
Good Luck I am sure if needed they will count you in.
Thanks for starting this much needed thread
