I got the PM and I looked at the website. It appears to be a combination of EddyFlower or SWPaddler, Facebook, and the Buzz. At this point it is difficult to navigate and seems to have an overabundance of information. It might be useful in the future. I think the goal might be to group people based on their local watersheds like Facebook groups and raise awareness.
