[Later. Title fixed.]
One of the oldest Internet communities for Unitarian Universalist Christians is the UUCF-MIN list. But as email has lost some of its cachet, and Facebook and Twitter have taken over some of its utility, the list has had less and less traffic, and now is more often quiet than not.
I sent an email to check in: to see if the mailing list is live, and to see if its former participants were still present and interested. They are. Some people, after all, just don't like Facebook or Twitter or any other social network.
If you are interested, and are a Unitarian Universalist and kindred Christian ministers or seminarians,in the United States or anywhere in the world, you are welcome to ask the moderators to join. (I think there was a provision for non-fellowshipped ministers who served denominational churches, but I cannot find any note of that now.) But don't ask me: I'm not one of them now!
