Basically, I think this forum is pretty self explanatory. Its for quick and simple snippets that people can copy and paste. Not really for complete classes or function libraries. http://www.phpclasses.org
are better suited for that.
This forum is also NOT for getting help with code. This is for completed and workable snippets of code often used.
The primary reason for adding was for something where I could store often used regular expressions, SQL databases, etc. Even better, other people can easily search through the forums for these code snippets, and also improve on them, and post a reply. So I think it will be useful.
On a side note: Do you guys think I am really pushing phpBB to be useful for more than just your average forum posts? Tutorials section, now a code snippet section? But considering that a forum is essentially (at the core) a "post and reply" setup, most anything can be use for it.
