Disclaimer: I do not support this plugin.
After my recent adventures with phpBB I’ve decided to switch to bbPress. phpBB has served me well for a while, but there are two major downsides: you can’t use custom PHP inside your template, and to install plugins you have to edit a lot of the core files. The latter especially sucks, so I went looking around for a better piece of forum software.
bbPress seemed like a good choice: small, easily customizable and a very usable admin panel. Unfortunately development has been rather slow lately and some basic functions you’d expect on a forum are still missing. Fortunately though, it’s so easily customizable and looks a lot like WordPress (which I have plenty experience with) that I was able to write some plugins of my own.
One of the most important missing pieces to me was the ability to hide a section of the forums from certain usergroups. As an admin, I want to have a place where I can discuss ongoing projects and other administrative activities with my fellow admins without everyone reading along. So I made a plugin that allows me to hide forums from usergroups I specifiy in the admin panel.
