As one of the leading anime artists on this site, heres my two cents:
I often wonder why anime was given its own section. I mean I know why, anime is clearly something different and special, not like toons. Its a different standard, a different bar and brings a different crowd...but not on this website.
However, as you say, there are not many new posts there often. In fact, there are more bumped threads than there are new ones.
I'm probably one of the few thats actually sustaining that forum with new content and original art. While it would be sad to have anime, which means alot to many people whether they openly say so or post, merged to become nameless and be bunched with the rest of the art and therefore lose whatever appeal it might have had as it's own forum, I agree that it should be merged in with the original artwork forum.
Preferably however as a sub-forum if thats feasible or desired. If its more trouble than its worth than no, they can just go with the other pictures.
EDIT:
Said change would also tidy up the forum and reorganize it. Furthermore, there will be no more double-posting of topics like there has been by several people (myself included) based on the problem that we see our art as original because it is, but its also anime. Thats why I myself initially starting posting in both. Then I realized it was more hits for me that way, and others realized that to, thats why they do it, not to spam or break any rule.
With this reorganization however, everything is in one place and that ensures that double-posting is not a problem and people will know where something should be posted. Taking this into account, my previous mention of a sub-forum won't work then, so it should not be created.
EDIT:
Also, I'm thinking maybe this should have been posted in the anime section. More people might post there. I myself wouldn't have known this thread existed because I don't come to this forum. I only knew it was here by looking at a profile and seeing someone else was looking at it.
Maybe you should move it.
EDIT:
I just thought of something else. If this forum is merged with the other one, people that did post for the anime content may not anymore, especially if they feel anime isn't being given a chance, or it's own place for whatever reason that might be. Perhaps some people only posted because they felt the anime forum was safe and seperated from anything else and that comforted them, knowing they wouldn't have to wade through other topics and art to find possible anime style art.
Basically, if they don't feel accomidated they may not bother. I'm sure some of them only came to this site and joined because it said it had anime tickling art specifically. For them to have to now do searches for that (oh wait, we don't have that and even that wouldn't work because no one labels their work as "anime" and shouldn't have to), rather, to have to again wade through other topics may discourage some. Though they could be passed off as lazy. I suppose if they really want to see the pictures that bad then they should be willing to invest a few minutes (depending on their net connection) to searching manually.
Its not an easy decision when you take all things into account like this, especially if you're considering the level of user-friendliness on this site in regards to navigation and the ease of that.
