When I had my 993 cab and 993 turbo I lived on Rennlist. I have never "met" a better group of car enthusiast. And the knowledge that was shared on the forum was invaluable. But, the Boxster side of Rennlist is very quiet. Babblers in No.Cal is dead. I just signed up for the PCA Boxster site and it too is very quiet.
For Boxsters, this is the place to be.
