i'm not entirely sure what point you're trying to make (sorry, english isn't my first language), But in my opinion this is a pretty well founded reason...
Isn't the point of banning ski-edits from skigabber to bring more viewers to the video-section and give honest people who simply post their video in the video section the same chances and exposure as some egomaniac who's plugging his own edit in skigabber ?
let's be honest, most edits that get posted on SG simply turn out in basically what is a comment list that could just as well be found/posted in the video section ...
Only a few are posted to really spark a discussion or ask a question, and those should still remain imho...
The threads that turn out as one huge comment list like "sick edit bro"'doopee!!' "i love it!" etc.... those should be removed imho, those edits belong in the video section without a doubt ...
feel free to make a better suggestion concerning regulation of edits in the forums, but i don't think that completely banning them is the way forward....
-Cheers!
