I'm in need of a forum plugin for Wordpress that has an option for a private forum that is only accessible (both for reading and posting) to registered users. Restricted posting appears to be de rigueur, but restricted viewing appears to be harder to find.
Ideally, it'll integrate directly with Wordpress but if it needs to open in a separate window (a la BBPress) then that's fine.
I've been looking around at different Wordpress forum options (such as BBPress and Mingle), but I can't see whether any support this feature.
Does anyone know of a simple forum solution that offers this? Thanks.
