These forums are listed on the homepage under 'related resources' and will continue to be as long as they are around.
I personally will not be setting up any other forums, that is for sure.
These forums and the section at linuxinternationals is the only refracta related forums I know of.
Sourceforge has forums available. If you wanted to explore that option. I am not sure if they are better/worse than these.
But you are officially the forum decision maker and whatever you come up with is fine.
