Hi Eric,
All three of your posts came through just fine for me. The first one got held a while for moderation, and I don't know why. I'm a little disappointed not to find some of the flexibility I'm used to from Yahoo groups I've been in and maintained. Specifically, I haven't found a way to say that you want copies of your own posts. Of course, you can always check on the web interface to make sure it arrived, but I'd rather not have to.
I can poke around on the google group help group some more, looking for answers.
Personally, I've been nose down in my other research (computer science) for a couple days. I'm looking forward to participating in more discussion in this new venue. Meanwhile, I really appreciate your energy!
Warmly, - Conal
