Looks like Windows Live Messenger isn't the only beta I'm running: the beta test itself seems a little broken.

When Messenger told me I had a pending request but clicking on the link popped up a window with no requests that also ignored the close button, I thought I'd let Microsoft know. Help > Send Feedback, though, led me to a page titled "Feedback Form Unavailable".

So, we're in a beta programme where the vendor can't accept our feedback about broken features because the feedback form is broken. Oops.

Update: When Kate tries it, she gets the right feedback form. So, I've left feedback about not being able to leave feedback. Oh, and the pending request thang.
