If you're going to have an open forum for development, may I also suggest using a public version control system? I've set up a
Subversion server for Europa Barbarorum, if you'd want I could set up one for AD/II as well. As a suggestion, you could have different access levels for core members, trusted people and general public (last one probably only read access).
You'd need some sort of server for it though which is always on and does not have any arbitrary limit of total traffic though, I'm not sure what your status is on that. I could set it up on my own computer so you could test it out but my connection drops out intermittently and is therefore pretty unsuitable.
