Since there is a new and rather big update of vBulletin, I'm working to update SPS pretty soon.
The new version will offer a lot new features like the ability to add tags to posts and things like creating social groups.
We will announce more of the new possabilities that will become available as soon as the update is done. And for who cannot wait look at vBulletin 3.7.0 'Gold' Released - vBulletin Community Forum

For now I plan to put the new version on-line coming wednessday. That means that the site will be off-line for several hours during the day.
