Jack, this isn't something that's earth shattering, but thought I'd say something. When clicking "quick links" while using Linux/Opera, the drop down menu goes behind the Google Ad, making it impossible to click the "Mark Forums Read" link. Works fine using Winders/Firefox.

 

Are you using the newest version of Opera? I don't have the same problem. Granted I am not runnin Linnux, but it was a thought.
