Welcome ActionAce1982, Andromedakay, et al.
As for me, I've been here 6 on TrekBBS just over 6 years and (a bit over 5,000 posts), having discovered it after several years posting over on the old Flare SciFi forums, which went sadly moribund quite a while back.
Although I'm not 100% certain, I'm pretty sure my first exposure to Star Trek was when it was in it's final season on NBC. I was 6. I certainly knew of the show by 1971-72 because I have a paperback book on dinosaurs on the inside cover of which I rendered a crude Enterprise.
It became my favorite thing around 1973 because it was of the fact that the animated show was on NBC Saturday mornings and the series was in daily reruns at 3:30pm, right when I got home from school. I saw TMP on opening weekend...twice.
