Apart from VirtuaGuy and Deskbabes, the only others they have as far as I'm aware are totemcash.com for webmasters and affiliates; hotgirlcentral.com which is more or less a promotion tool for affiliates; plus a site called "VIP Room" which offered erotic videos for a subscription, but is no longer maintained as I understand it, although it's front page at least can still be viewed.
Deskbabes and VirtuaGuy are more or less add-ons for VirtuaGirl. You have to install Desbabes and/or VirtuaGuy over the top of your VG installation, and after that you can switch between the three collections (and their alternate skins) from the same user interface.
The latest release of the new beta is completely irrelevant. DB and VirtuaGuy work just as well with the current official release - Version: 1.0.6.01
@nickhil - if your not not sure of your facts, it's best not to say anything, rather than giving out misleading information.
