Once a proposal is in commit phase, there's no way for the participants to communicate with each other (as far as I can tell). When the proposal goes beta, an e-mail gets sent out to the committers, so some list exists. My question is: is there any way to e-mail the committed participants prior to this?
Now, of course, this is a recipe for spam, and would have to be done very carefully. But my problem is that I'd like to get a sense of the community regarding a proposal that I'm heavily involved with — I didn't propose it, but I've been promoting it a bit — and currently there's no way of talking to other committers. I'd be happy to share my e-mail with the relevant moderators for approval so that they can verify that it isn't spam.
