Keel Framework maintains three lists:

Announcement List
very low activity (few times a year)

User List
moderate activity (activity level not established yet)

Developer List
very active (as many as dozens of messages a day)

When responding to a question, please remember that the easiest place to look up documentation is on the Keel Documentation Wiki instead of email archives.

You can now also read messages from the Keel list via your favorite news (NNTP) news reader:

The Keel User list:
news://news.gmane.org/gmane.comp.java.keel.user

The Keel Dev. list:
news://news.gmane.org/gmane.comp.java.keel.devel

The Keel Ann. list:
news://news.gmane.org/gmane.comp.java.keel.announce

You should also be able to post from such a reader, but this has not proven to be successful in all instances.
