I have just created this group. My name is Ken Anderson. I am a Christian and the administrator of a discussion forum for seniors, fifty and older, which I will link to below.
My forum is not restricted to Christians or conservatives, although there are several of us there.
The forum requires registration, but there is no charge for membership. We use first and last names rather than handles. Pseudonyms are acceptable as long as they look real.
