Is it possible to do this with vBulletin
 

i run a proxy website and lately its using alot of bandwidth in excess of 140gb a day...
and im pretty sure its not all people using it, just people leaching the connection.

so i was wondering is there any way i can integrate its functions in with my vbulletin board, so that they have to sign up and then they can click on a forum that redirects to the proxy files.. but at the same time having to be signed in to view the files.

the proxies files are written in php.

if any one has a solution i would love to hear it..

can any body help me with this or even give me an idea?
