The Arquillian project [1] would like to volunteer to be an early adopter of HyperKitty. We are looking to shift from forums to mailinglists, but not lose a user-friendly web frontend for folks just browsing for information.
We're writing to this list because we think that Fedora and Arquillian share a common goal to see HyperKitty evolve. We can offer to hack on it and promote it if Fedora infrastructure would be willing to give us a space to run a public instance of it. (We're also Fedora users, of course).
We know about mm3test.fedoraproject.org, but we're hoping to be able to point discuss.arquillian.org at to the installation (CNAME support).
