The [new] list of the Language committee [1] is now open for read-only
subscribers. The new archives will be open.
During the previous two years any valid member of the community could
apply for observer status. Since a week ago, everybody can follow the
list.
(I'm not quite sure if this information has been already published on
this list. If so, sorry for sending it twice.)
