Topic: CMS Made Simple module
I've just built a preliminary module to integrate PunBB with CMS Made Simple (http://www.cmsmadesimple.org).
It uses PunBB for the forums, obviously, but I also integrated the PunBB user and group database to provide for user-side access control over all the content in the CMS. By placing a tag in a page template, it comes under access control. In the CMS admin area, you can assign access rights to the PunBB groups on a page-by-page basis.
It's a little crufty, and will need further development, but I just wanted to let the community know
