Hi Matt. I lurk here from time to time, and n odoubt that you are "the man" when it comes to Commotion.
But there's alot of folks over at the Avid (previously Pinnacle) discussion forum who would love to have you talk to them about Commotion, because many of them still use it because the XSEND tool in Liquid Edition works well with Commotion.
So, I was wondering if you could make yourself invited over there and make your presence known to us? They also have a forum for things for sale, and you could post your training DVD and maybe get some sales.
Thanks for the offer. Unfortunately it is difficult for me to keep up with different forums, which is why I stick to this one. We get very few posts here, and they get emailed directly to me. If you would be kind enough to refer people to this forum when a Commotion question comes up I will be more than happy to answer questions.
