I have been a member of the autox.team.net Healeys list since 1996. Participation in that list in the last few years has been dwindling, and now even when the list is up it seems not to have much traffic. I've been a member of BCF since 2001, but spent most of my time on the autox list because it better met my needs as keeper of the BJ8 Registry, and I didn't (don't) care for the tendency of forum members to rely on pseudonyms and and some to remain anonymous. I never really understood why people felt that way, since we are all in the Healey community together.
There are other Healey forums (fora?) now such as The A-H Experience and special groups on Facebook, but my personal opinion is that they just dilute the overall effort. I've noticed that people on some of the other sites are asking the same questions that have been asked here and on the Healeys list. Someone directed me a few days ago to the forum at A-H Experience where a poster was commenting on an apparent error in my procedures for adjusting the HD8 carburetors. If that issue had been posted here, I would have been able to respond in a more timely manner.
Just my two cents worth.
