Hide username in private forum

[A.T.F]

Hi,

I'm very new to this so please do not bite my head off if this has already been requested or not possible. I was wondering if it is possible however to hide the username of the last poster if you have a private forum that you do not want other people to see. I know you can make a forum invisible, but i dont want it invisible, just very secure.

Thanks

Set "Hide private forum" to Yes in vBulletin Options, and then private forums won't be visible to those that cannot access them.

But if i don't want it to be invisible, is there no way of fiddling about with any templates to hide the username of the last posted user, maybe just to say (Last post at 12:55pm) or something like that?
