When pc will upgrade its forum script as new version of vbulletin has been released and can be downloaded now from vbulletin.com via members area. The new one really has great features and i think it would be great to install that at pc. You can see the demo at vbulletin.com. It also allow us to make friends like we make friends on hi5,orkut etc. It also allows you the feature of scraps which is knows as Visitor message in terms of vbulletin. All the new options like tagging etc are there in it.
