Hi Mist,
I'm also one of the developers over at vbportal aka scotsmist.
Always interested in new add-ons and additions that would benefit vbulletin users. Bring your ideas forward
As wajones mentioned the latest beta version of vbportal is much less server intensive and can now easily be configured to use far less queries and resources than previous releases. The installation has been revamped, there are new, improved admin manual pages and a lot more modules have been ported too.
I don't want to turn this into an advert (sorry, it nearly was), just wanted to also extend our welcome and appreciation to vbulletin fans/users everywhere.
