I have just joined this organization and I do not want to be a Robin Williams in Vietnam but wouldn't it be nice if we created a repo just for communication? We could ask things via Issues and people have the option to opt out. We could use a mailing group (which I can volunteer to set up on my web server) however Issues on github would be public and have the option to be referred to and flagged as closed or tagged and what not.
I could provide a opt-out-able mailing system too, however since we are already on github we could use the system there and grow the organization into a little knowledge base...
All of this comes from me looking for a way to ask others on github and to be able to attach code on github or even link issues from our plugin repos.
Do you like the idea? It couldn't hurt right?
