If you've been managing your Premium account to stay within the 250 page limit, you can take it easy now. The limit for Premium accounts has been raised from 250 to 500 as of this evening, which should be more than enough for the great majority of sites being tracked. No charge for the upgrade!
I've also got some more servers on order. Those are supposed to arrive later this week and I'll be using them to beef up both the web counters and the member area of the site. I'll also throw a new database server into the web hosting side of things, just to keep things fair. :)
