Wiki Formatting issues, but only when logged in
 

I've checked this in IE6 and FireFox 2.0.0.4, so I think it's something on the wiki site, and not my browser. Originally I thought I just wasn't getting a style sheet or something.

I notice that when I am looking at pages on the wiki when logged in (as required to do an edit) then the page rendering is different. Some things are good, some not.

When logged in:
Much of the surround-based formatting is lost and all fonts seem to default to a Times New Roman 12pt. The tabs at the top for article/discussion/edit/history are turned into links as are the links on the left (bulletization is removed) and there's no longer the grey background.

When not logged in:
The title of the article is not shown on the page itself (though it is there when logged in).

I think the root of this is that there's a different stylesheet or processing rule in the background -- I can't find any user setting that causes this. Maybe I missed something or this is intentional, but I couldn't find anything else talking about it.
