Finally, realize that not everybody on a list has high speed access to the Internet. A large attachment can cause all sorts of problems for somebody on a 9600 or 2400 baud e-mail access.

This is a form of entertainment as well as a source of information much as the forum in Rome served both to inform and amuse. Please remember this in all of your dealings here. Note that the reply to address of messages generated by this list manager is that of the original writer. If you wish to reply to the list for all to read you must explicitly choose to do so. The reason that this policy has been adopted is to prevent problems relating to bounced message traffic from flooding the list and to reduce the occurence of private e-mail from being inadvertently made public.
