I guess a mod would have to keep that in check.
Which means that instead of you having to look and sort the posts, that's a job that would be issued on mods.
And, as far as I'm concerned (and only talking in my name), that's some time I can't spare/job I'm not willing to take.
I hardly look into the "your creations" forum, and have already enough of moderation/moving/answering topics/posts around in the other forums.
You'd be surprised the number of topics that need to be moved because newcomers (and not so newcomers) just seem to not care about the structure of the forums and post wherever they want to.
