i may be being a bit dumb here, but i can't see any way to register...
[edit: also, clicking top left should always lead back to the front page] [and you shouldn't be displaying "shelves" on "about" to people not logged in] [and now someone else has registered it anyway]
(thanks) ok, another small bug - for sufficiently narrow browser windows the registration links are not shown (just drag your browser window narrower and you'll see them disappear). you need to float right or similar.
