Recently some people wanted to post to this mailing list, but didn't want to sub-scribe. Since this list allows posts only from subscribers, this was a problem.
Therefore, I've now set up an experimental web posting facility. It is available under "Mailing list archives" on the web site. One can send a new mail from the main archive page, or reply to mails in the archive.
If this service starts to be abused by spammers, we might have to stop it. Let's hope this doesn't happen so soon.
