posting restricted to subscribers

[Matthew Flatt <mflatt@cs.utah.edu>]

The web page for the mailing list has always claimed that posting is
retricted to subscribers, though obviously this has not been the case.

I finally got around to learning how to restrict posting to
subscribers, and it's done now.

Depending on how many mail accounts you use, this could be a pain
(i.e., if you send mail from an account that isn't the one where you
receieve plt-scheme message). Hopefully the reduced spam will make up
for it, though.
