??? If you want to discuss an issue, you've got to get messages,
right?

You don't ned to subscribe to the list: if you participate in a
discussion, the messages are sent to any participants, whether or not
they are subscribers.

> Is there also a web forum or newsgroup for these topics?

No, only a mailing list.

What happens if that function is called on some other DOS system?
That is, how can we know we run on DR-DOS 7.x or higher vs, say MS-DOS
6.22?
