Hiho,
I believe it is now time to report bugs a bit more systematically. So, how do Aaron and Joerg want it? Use Bugzilla? Use a discussion page on the testwikis? Or simply use this thread on the mailinglist?
If the last one is fine until now, here is the first bug ;-)
If I'm not logged in and the current revision is sighted, I do see the currrent revision, but still have no edit button. Thus, when I click on current revision, the version does not change (although the edit button appears). Furthermore, the "Current Revision"-Tab does not disappear. IMHO it should be that, first of all, the current revision tab should disappear and the edit button appears instead and furthermore, if the current revision is the default one, the edit button should be there immediately.
Bye,
Philipp
