Some Forums visable to some usergroups but cannot access, While some Are Invisable?

[AnaSci]

i posted this on VB.com and it seems as though it cant be done... could anyone engineer a hack for this or point me in the direction if there is already one?! THANKS!

Some Forums visable to some usergroups but cannot access, While some Are Invisable?

is there anyway of doing this?

for instance,

My MOD forum is visble on the main page by all users, except when they click into it, they cannot see anything, it says they arent allowed in there.

(i also have donated member forums which are set like this and MUST stay visable! hence the need for the hack to make select forums invisible)

i'd like to create an ADMIN forum, that the mods and other members dont know about/cant see or access

is this possible? or do all private forums have to either be hidden or visable

thanks
