<p>I would suggest to put extra code (e.g., that won't fit in an ordinary response) as dedicated <a href="http://gist.github.com/" rel="nofollow">Gist</a> on Github. Don't know if you could manage to hold a public repository for the whole site or if each individual shall create his own account. Anyway, this is very great to share code snippets, with automatic syntax highlighting, revision history, with support for comments in Markdown. </p>
