Hi Rob - I was pretty busy with my freeplay pins at the show but I was also helping out at the Pinball Gallery booth which was right next to yours at Allentown this year. We spoke briefly Saturday afternoon (I think). I must admit that I had no idea you were offering seminars, sorry! Not sure if i'd have had the time to attend but I certainly would've tried. I know that smaller vendors have a tough time trying to get attention in the middle of the show chaos but I hope you find a way to get word out! I'll be sure to look for you again next year.
Steve
