I didn't know we had special permissions

I think you may misunderstand - For example, if a regular user wants to upload a 1.9MB .exe file,
after the upload we are told hat the extension is not allowed, what i'm getting at it is that can we get that warning prior to it uploading and not waiting a few minutes for it to upload only to be told it's not allowed.
Any-whoo, if you're considering removing the upload feature permanently, not-to-worry!
