Its taking up about 100-150 megs on the server, i had it way too high and its full of junk files.
At the rate of the forums growth, I'm going to run out of space in a few months.
I reduced everyones upload max to the following:
Member: 400kb File Size/500kb Total Size.
Loyal Member (300+ Posts): 800kb File Size/1000kb Total Size.
This is more than okay for uploading multipule images, and maps when needed
