This is just an FYI of something I noticed. If you are still planning forum changes, I wouldn't classify this as big enough to need to worry about yet, but I wanted to give you a heads up anyways.
If you log into (or out of) your account on the Forum page, your log in status for the main page is not updated.
The same is not true in reverse. Logging in or out of the main page updates the forum log in correctly.
