There are several mailing lists out there for Edenites. All the ones I'm aware of are conducted through Yahoo Groups. You can go there and do a search for "Earth 2" or "Earth2". That will give you a list of mailing lists you can join. Or you can go directly to any of the links below to sign up.
These are the lists that I am aware of, as of March 25, 2013. I won't recommend any of them over any others, but I believe the first three listed are the largest.
