Size was the wrong word to use as I was referring only to traffic as reported by Alexa. WHT is obviously much bigger in membership, posts, etc. I also understand that Alexa is far from being a precision instrument, though it can be useful for a broad view of traffic trends (especially if you factor in results that are skewed by the large # of domainers who run the toolbar). WHT also took another big step up in Alexa ranking this week (1700 range).
P.S. to Onyx - you appear to have wandered into the wrong thread - The Assholes Anonymous meeting is down the hall.
