- fix [flash], add width/height parameters?
- check that PHP syntax highlightning works well
- add other languages?
- add validation regexp to [email], [flash]
- need size limit checks on img/flash tags ... probably warrants some discussion)

- add other languages to syntax highlighter
- better (and unified, wrt other pages such as registration) validation for urls, emails, etc...
