Latest modifications:

Atom 1.0 feeds added.

Forum level 'Recent comments' added (previously this was only available on weblogs)

Photo albums released.

Photo collections will be automatically unpacked if uploaded in either 'tar' or 'zip' formats. This is ignored if any member files contain relocated or absolute path components. 

New theme - 'darklord'

Added action icons on user/member page - detail view and adult interaction (if configured with $ALLOW_SEX) 

Feeds now contain the entire message payload within the respective body element. This includes comments, comment avatars, comment links, and attachments. I was dissapointed how many external aggregators fail to handle attachments consistently (or at all), and very few use the 'comment' RSS element (at all). This allows an accurate content mirror using standard feeds.  

Forum table implemented. (Previously forums were article attributes.) This allows forums to have descriptions and  permission structures, although more work needs to be done before forum permissions are turned on.

Help page for compose is back after a lengthy absence.

Security: Uploaded PHP files are converted to .txt

Fixed a couple of typos (main page and 'members') that slipped in which rendered correctly but gave the w3c validator some grief.
