[wp-forums] Forum login changes

[Otto]

For you moderators and anybody else with access to the admin sections
of the forums, you may find that you can't access them anymore. Don't
panic: Just log out then log back in.

I've fixed the single sign on cookies so that they share properly
across all the various sections of wp.org (minus /extend/themes and
codex, at the moment). This means that while your login cookies
haven't changed, your admin authorization cookies have. So until you
reset them and get the right cookie, you (probably) won't be able to
get into the forum admin areas.

So, log out then log back in before trying anything else. If that
doesn't work, clear all cookies then log back in.

This should only ever be required once, to get your cookies
straightened out right.
