It must do similar to what is already offered by the version found on their website / vbulletin free version... I would hope even done better by the coder who takes this on, considering you have a far better core to build upon. I believe the only difference between the free and paid is the branding notice.
It must be public here and supported... for everyone to use, obviously launched and fault found by members who choose to use it. I will gladly then donate the above to the person who achieves this... being a stable version.
