After .Astronomy 4 several people asked if we could keep the shout@ mail exploder alive. During the conference this can be very useful, but it’s not a good long-term solution as it provides a way to mailbomb everyone and no one can add/remove themselves from the list easily. So there is now a proper .Astronomy mailing list that you can join at http://dotastronomy.com/about/mailing-list/.
If you want to be part of the conversation then please request to sign up. For the time being we’ll only be accepting sign ups from people who have attended a past .Astronomy meeting . This is the keep the conversation manageable and focussed for the time being.
