I seem to remember seeing a site for this specific purpose, but Google is unable to find it, so it must not exist (just kidding...).
I know that I will be hosting code of my own off our team website (
http://www.trucktownthunder.com/). That just seems the logical place for it. I just don't have the free time to put together a PHP system for uploading files, creating tutorials...I'm imagining something along the lines of CD-Media, except much more souped-up and targeted at programmers.
Just throwing out ideas at this point.
