About a week ago I sent four mails to this mailing list without being subscribed. For each mail I got a reply that the message awaits moderator approval. After that I subscribed to the list, because it is low volume, and I want to spare the moderator some approval work. Shortly after that my subscription to the list got approved. But to date the messages sent before did not appear on the list. After waiting for a week, I revised the four messages and sent them again. So the not approved mails are obsolete by now. Since I assume that most moderators would not approve me subscribing to the list after I sent four disapproved messages, the most probably thing is that the messages got lost. I.e. sending mail to this list without being subscribed currently is not possible. Best wishes Sebastian
