Wow. I had never planned that. I simply wanted the Zimbra-repository to not be owned by me alone, so I've set up the Community organization. But I never actually thought about making that some sort of "hub" for Zimbra-related projects.
So, good idea. I've added you to the community. If you'd like to move some of your repositories to the organization, tell me and I will initiate that.
Besides that there's actually nothing to do right now for the community. The Zimbra-Repository is a simple "fetch from p4 and push to github" job running on my server.
