I’ve detailed and completed the instructions for installing and configuring the Forums Web Part for your systems. There’s been a lot of people who have either never editing web.config to add SafeControl entries, or never created a custom security policy file and are a little lost in step 3 or 4.
You can find the complete instructions here on the CodePlex Wiki. Each step contains a link to a more detailed page outining what has to be done (with examples). Hopefully these instructions are complete enough for everyone.
Yeah, the system really needs an installer.
