Pretty much only Uatu and I use that forum, though there are a lot of people registered...I do think all of the people involved in the project are registered.
I've felt for a while that this project is "dead" for most involved, but let me assure everyone, I'm still working on it.
For the next release, I will be adding another section that I've been working on and might even have to start on a third one...this is the place where I put all of the little snippets of ideas I have that aren't big enough to warrant their own design...
