Hi,
The Openbook users list that has been around for years has not been properly
moderated in several years. No one has been minding the group so no new
members have been added. I, and others that I know, have tried several times
unsuccessfully to join and our attempts have always timed out without anyone
acting on our join requests. However, there is another one that has only
been around for about two years and is on groups.io so it is rather small
and the traffic is light. But at least it accepts members. And when someone
posts there is usually a response.
Openbook+subscribe@groups.io
Is the subscribe address if I am not mistaken.
Hope that helps.
Merv
