Helping Others

I have a ton of code snippets I'd like to upload to help a lot of posts on this site but apparently I'm unable to upload them (they are not very big in size and it seems I've reached the maximum I can upload). I'm trying to learn the rules of this new forums site (I usually get on dbforums) but I can't figure out how to remove some of my uploads to make room for new ones. I guess I don't realize why there's a size problem with the price of harddrives these days but I'll keep trying so I can post help out others.
