For now, all news will be posted on the main page.
Right now there's only one mailing list, "binars-announce", on which I'll post announcements about new releases and other pertinent information. Only I can post to the list without approval (from me), so it should be very low traffic.
If there's enough interest, I'll set up users and developers lists as well. I'll decide this based on how much mail I get about the program. So if you want more lists, drop me a line; lists are easy to set up.
