I am playing with the forums plugin, and it seems fairly restrictive.
We are trying to find a forum like plugin that would allow a few sections, with the ability to do private/public flags. And last but not least, work with multisite, and look good in general.
So far, the WPMUDEV Forums plugin seems to be fairly simple to use, however, no Widget to display open topics, and the way to privitize it is to simply put on a page thats private. Except, then people cant see the topics.
Yes, ideally they would just install an actual forum should they need it, but unfortunately theyre trying to use my multisite install.
We've tried BB Press. The private forums disappear unless logged in. The visitors are.. visitors, and just dont get that they simply need to log in.
