When I was brwosing the web I found this forum:
How about a similar forum here, devoted to source code. We could post code snippets and small projects (0-100KB). Then when people viewed and used the code, they could post bug fixes, comments and variants of the original as replies.
People could post links to threads on this board when similar code is requested.
Code would be either posted as the message text or an attachment. The language/OS of the code should be specified in the subject.
