#13,544 since Oct 23, 1998. Actually I was bit by one of the server crashes and had been on before then for about two months.
Like many, I lurked during the heady days of '98. At the office, I read the threads during lunch and breaks. Finally, in a chat room in the evening with Yellow Rose of Texas, amom, RAH, Towanda, LisaFab and others, Rose encouraged me to open a niche in the firewall and register, so that I could participate. That was May of '99 but I had been following the drama since about March of '98. I was here for DTHF, the night of the long knives cadre revolt, AshAlerts and all that silly stuff.
What a great thing it was to watch the lead-up to the impeachment and the drama of its unfolding.
