I had a problem with users getting an "Access Denied" error. It took me a little time to realize that I assigned the wrong permissions to the anonymous users.

This being said, the problem is bigger than it seems, I think...

I would expect a user who goes to the chat page and who doesn't have rights to post to not see the textarea message box where they can then type a message which is refused in the end. I turned off caches on that page, so I would think that the cache is not a problem.

It's getting late here, but I will look in the problem tomorrow. I actually like the idea to let anonymous users see the Chat and when they want to participate, force them to log in. (register if necessary)

Thank you.
