I submitted the previous message, but I did not realize that only list
members could post without moderator approval. I received notification that
my message awaited moderator approval, but that notification did not
specify how long the moderator might take to approve; so I have joined the
balsa-list@gnome.org mailing list, and I am reposting my initial
submission. I apologize if this repost results in a message duplication.
