do not use vBulletin in your site name.. .this is against the copyright...
also, "giving back to the community" is not a reason to start a forum.. the best way would be to collaborate on this community instead of spreading the efforts to make it better...
when you have time to loose, instead of starting a place where people will not be supported properly or having a site just to have a site, please do it for products that do not have already a great support...
if you do not want to duplicate anyother vBulletin content, why do you start that forum then ?!
that makes no sense...
even me with the experience i have and the presence i have on the vbulletin community i would never open a site like that to "give back to the community"... it is more logic to participate here... anyway, this is the only official support forum.
This post has some valid points....
My thoughts are the content matter is already at vb.org vb.com so this site will have huge problems getting going.
