Where did you post (what forum/thread)? I noticed that your first two posts didn't show up when I check what you had posted...
In the artist sections 1-9 and L I was looking for Move Bitch and In Da Club. I found move bitch but when I click on the 50 cent threads the url isn't found.
I am not sure right off hand, but I don't think that you can post in the Artist sections of the Midis...I will check though
The "New Songs" forum is moderated in a way that no post will appear until it is checked by the powers-that-be..... you wouldn't beleive how many people mistake that for a request forum!?!??!! Dunno about the 'not found' issue........
