Just thought I’d register a resolution on the whole logged in thing here. We’ve got some new code that takes your registrations and can indicate what your status is.

You’ll see up on the left, just under the Search box, a couple of links. If you’re logged in, it will give you options to go to the Site Admin - just a fancy way of saying the place where you write posts and stuff - if you’re a contributor - and a link to Logout.

Otherwise, you can Register or Login.

You might also like to know that the following messages appear on the commenting page to tell you if you’re logged in or not:
nolog
and
logged in

And that should make it easier for everyone.
