How often are they updated?

I have just checked mine out (out of boredom) and what is displayed doesn't really make sense for my current posting activities. I am guessing it is 2006 stats. Also, when I add up the total 2006 & 2007 total posts - it is still more than 300 short of my actual posting figure.

Just wondering about it all ...

Please move this post to Technical if it should be there!
