having used the forums a lot lately (and loving the work you guys have done recently!) I think the one thing that makes communicating code that much harder is the lack of syntax highlighting. If we had that it would really bring the support up a level....at least if feels like it would.
How difficult would it be to implement a highlighting script like this one?: http://scott.yang.id.au/2003/01/source-code-syntax-highlighting-in-php/
I see what your saying about making posts long, I know some of mine have been pretty monstrous. But at the same time sometimes it's definately worth posting a short function or two rather than linking externaly just to keep the post flowing.
I hadn't used pastie before but it looks pretty useful, I will start using it for my longer posts (although I couldnt get the highlighting on that to work either :( )
