A couple of days ago I noticed that the revisions I made to a page were labeled as being made by an anonymous user. I was testing iCab for Mac OS 9 at the time so I thought it was a browser thing. But now I'm using Firefox on Windows and it's the same thing. This only happens when I do revisions such as the one I did a few hours ago to The Colony, but not when I create a page like when I uploaded Star Wars: Rebel Assault.
By the way I uploaded five pics to that page and yet only the first one shows up. The others appears as a text link that simply says "Screenshot." Yet when you edit the page, the other pics show up fine.
