Petfish.net I would say is the best that I have found, they have a lot of forums, like I think 23, about all different kinds of FW stuff. They do have a SW forum to.
I'm actually coming from the Hydro side and i just took an old device that i have - AquaDyne AquaNode ES 500 and i'm looking for the AquaWeb SW - anyone still have a copy ?
