I may not be the best welcome committee, as I've been dormant for over a decade until the past few weeks...but welcome!
Hopefully there's still some life in the ol' forum. I prefer forums to facebook for these sorts of things, but that doesn't seem to be the general consensus.
Up until this past May I had 3 cars. The FR-S still has a pretty active forum. The Datsun Roadster actually had an active forum, and the '00 Celica...well, newcelica.org was pretty slow.
Anyway, good luck in your search!
