There's something I don't get...
Irrlicht is a graphics rendering engine...you need the code, you need the graphics...
There are sections for several flavours of coding matters, not only a general "coding", which would be the one we're proposing here for game artwork...
But even, there exists: .net section, code snippets section, Jirr section...but artwork has to go to a sort of Offtopic section where many ppl don't even care to look... is that the concept on the art of actually making those nice 3d models with normal maps and all the nice things to make your game look great...that's something with sure will make artist fly away very far...
Ogre forums do have a section like we're talking about... right in the first big section there's a clear one called "Artists & Content Creators", and dunno as don't frequent those, but in all forums I knew about these matters, games, projects, and artists help, growed exponentially from that point... And no fear tehre'd be no questions, as , by far, questions bout handling blender, x, b3d, and huge etc, fill the forum to crazy limits (indeed would help to keep your other 11 forums sections clean of that smelly art thingz...)
Just is better to view... :
http://www.ogre3d.org/phpBB2/
here, even a big section with subsections
http://www.garagegames.com/mg/forums/re ... a.php?qs=1
blitz3d (content creation tools and art showcase)
http://www.blitzbasic.com/Community/_index_.php
Dark Basic Pro ("3 dimensional talk", "2d all the way" (I'd have merged in one..yet has sense as they had a product more 2d based, and usually sprite makers aren into 3d...I'm an strange case, mwahahaha...))
http://forum.thegamecreators.com/?m=forum#1
Crystal Space engine, probably next Blender game engine..see, even having so many sections, is directly the third section...
"Game Content Creation" "All discussions on the creation of textures, 3D models, sound, music etc. goes in this forum."
http://community.crystalspace3d.org/forum/index.php
[ I mean, shouldnt even be needed a poll...plain logic...But I don't see bad idea making one...then again, as most here are programmers, and many don't care about art (till they need it, mwahahahaa), poll probably will be negative.Anyway, life is so

Yet tho, moderators do not have to do anything , they work for free, and besides, server can have problems for that , I dunno...I am talking only about the abstract concept on it having sense or not, and how much it has been proved it's essential.
And I dont say for me to post, as some know, am doing a project with a sort of home made engine, yet i think would be important for the comunity.
