I saw that yesterday too using IE6. And I saw a couple problems (?) just now on both IE7 and FireFox 220.127.116.11. There is some white space (rectangle) in the upper-left corner where an add probably belongs, and in the lower-right, just beneath "Todays Posts" (no posts listed)
Well, I was poking around control panel, checking the notification status (set on instant)....checking my e-mail address (that hadn't changed)..... tried to change my e-mail address to the yahoo account... failed because it is in use (by my alter ego that is still not deleted, but came in handy now).... created another yahoo account and changed to that one.... supposed to get some notification....and didn't get it....so, I changed to my previous hotmail account.....(you guessed it) didn't get the notification there neither.
And, whaddayaknow, my account here ceased to be active! I get that activation message and that says "You can have your activation email resent to you at *my email*"...Oh, the irony!
