A lot of people have been signing up lately, but none have joined into the discussions.
I encourage you to do so. Feel free to make comments on the pages, blog posts, and the forum.
Also, there is an internal messaging system that you can access when you log into the Dashboard (you have to be a registered Member for this). The messages are not encrypted or secure in any manner, and the system is there as a convenience only.
Feel free to explore and participate.
