vbulletin minimum posts before posting a link

Hi

Does anyone know how to do this say user must post at least 10 posts before being able to post a link, as a deterrent against Spammers?

Thanks

 

there is a hack by cybernitics that will allow you do to that
you can get it at vbulletin.org

 

THIS will do the job..
(Its the mod that Brandon mentioned above)

 

I use this as well, it helps alot to keep the spam down.
