I have not, in fact, met jingle. Or many others. Although I would love too.
I met rumborak and a host of other older members (who are largely inactive here now) at the DTF meetup in New York on April 1, 2006 (before the RCMH show). In addition, it is my understanding that several people who are still active were there also, but we didn't meet - it was a large gathering, and I was still fairly new to DTF.
I also met vtgrad at the local showing of Live at Luna Park. And I met DrDTVT in my city on my birthday a few years ago (he happened to be travelling through, so we met for lunch).
