OMG. I posted this a long time ago. Umm.. I still might work on this hack. I been busy with my website and for one of my sites I been creating a simple forum so I totall forgot about this hack. My other site uses vB though.
So... untill my mind is back on track from school, other stuff, etc. this project been on hold. So... umm... cya!
bria... i think this is still usefull but I havn't look at the 2.0.1 and on updates and have no idea if they added passworded forums yet. I think they did or maybe not cause 2 sites I visit often have this feature but if it isn't included I plan on getting started on this right away.

Cause an access list is easier than passwords with cookies and stuff.
