Abuzz - late autumn 1999. I followed a link from the New York Times at the end of a review of an off-Broadway production of a Wendy Wasserstein play ... there was a question at the end of the review ... something along the lines of ... would you be interested in discussing this with other people ... I'd declined a couple of previous similar notices ... decided to click on the yes.
The link didn't take me into any kind of theatre discussion, but into some sort of exercise discussion ... there was a challenge as to how many sit-ups people could do. I posted my results, then started reading around the site.
I started here hmmmm early to mid-September 2002 as I recall. I spent a day or two mostly posting to myself or Roger as no one else had joined (or couldn't figure out how to log in).
