The latest version of the software that we use to run this forum (vbulletin) was released from beta a couple of weeks ago. I have been working on getting everything installed and upgraded and it's just about done. Since this is the first forum I've installed it on since it went out of beta I'm not really familiar with all of the new features or exactly how they work. Anyone that's interested in this stuff can take a look at the software vendors descriptions: Thread tagging Search cloud / tag cloud Thread prefixes Reciprocal friendships between users Public visitor messaging on profile pages with 'conversation' feature User picture galleries with user comment facility User-created social groups with invite only and moderated membership options Extended member profile pages Customizable member profile pages with admin-controlled styling abilities Inline editing of custom user profile fields Lightbox viewer for attached images Most of these things are available for tweaking in your User Control Panel. The thread tags are visible at the bottom of the thread.
