MFC has an active email discussion group, firstname.lastname@example.org having over 500 members. The discussion topics vary widely, but are generally limited to issues related to public health.
It is a self-moderated group, with some restrictions on membership.
To join the group, one needs to be introduced by an existing member of the e-forum and seconded by another member. If you wish to join the group but are not known to any existing members, you may write to the moderator (email@example.com) and request to join the E-forum group, with a detailed self-introduction.
The moderator will forward the request to the group, and who knows, there may be some member who knows you and is willing to propose your membership!
