With the help of r-a-y, we put up a tutorial on how to set up a single bbPress forum without doing a separate install. The drawback is it still uses a Group, and it means you won’t be able to use Groups for other purposes while this is in place. The upside is it’s fully integrating bbPress, so whenever the updated plugin comes out you’ll be in good shape.
We at buddyboss.com just started using the CustomPress plugin by wpmudev.org — http://premium.wpmudev.org/project/custompress . It lets you easily set up custom post types and custom fields in WP admin. So far, I’m absolutely loving it.
I was pumped when I first heard about WP 3.0’s custom post type functionality, and THIS is what I assumed would be coming. I’m not a programmer, so I need a UI to set up custom post types. This lets you name a custom post type, choose where it falls in the WP admin menu, pick the icon, pick the fields and editable areas that will display, and create custom fields that will be requested on any post type. It also lets you create custom taxonomies, which I haven’t used yet.
It makes WP/BP into fully legit CMS, rather than a blogging platform flexible enough to be used as a CMS. This will be seeing its way into a lot of our client projects.
