Lots of updates this time: the JavaScript has been made more modular and moved into an external file.  This was at the expense of some functionality that has, unfortunately, been moved server-side.

Whilst working on Need To Talk I discovered a far more efficient method of data-validation, so that side of the site has been updated too.  A profile page now exists allowing users to: change their password; see a list of forums they've started / contributed to; and to edit the signature that is automatically added to their postings in the forums.
