It's really good to see more and more folks joining up with the group. I've been online quite a bit recently and have noticed an increase in the number of visitors on the site, too.
I've been a part of several discussion groups of this type.....people sharing a common *interest*. A forum of this type can be an absolute TREASURE of knowledge and experience and innovation. Take a look at
http://www.smokstak.com/forum/as a great example, or the microhydro yahoo group. People from all over the world with a common interest and a quest to know more about it.
In the really successful and interesting and informative groups that common interest is NOT profit. Think about it, please.
