Thanks for the input Willemina
I wonder if VBulletin could be used as a one stop shop for creating social networks now? Could a VBulletin site become a competitor for FaceBook, MySpace, Bebo etc? Obviously there would need to be some serious themng and a bit of custom coding to get it working properly, but it doesn't seem entirely impossible to me. Most of the features are there. And VBulletin is presumably able to run across multiple servers fairly easily (or as easy as that type of thing gets) so scaling should be fairly straight forward.
