To the group:
Hi and congratulations. Not so much for the knowledgeable membership: lotsa folks have experience with the Corvette. Not really for the humor, although that's important too. What I'm giving you all a pat on the back for is the tone or attitude I find here.
It's mature. For an older person, that's refreshing and rare on usenet. I checked out a few forum-type sites, and for me, the fixation on nitrous, lowered suspensions and the "politically correct" carwash product just wears thin after awhile.
It's friendly. Even when somebody starts to get overheated by a perceived insult, it's quickly defused by the laid-back banter of the regulars.
And as a bonus, you talk more about Vettes than you do about politics. I love that.
