  1. How do I unsubscribe from MacGroup or MacGroup-Digest?

    Go to the list information page at
    http://www.math.louisville.edu/mailman/listinfo/macgroup
    and fill in the form. The option to unsubscribe is near the bottom.

  2. How do I change the email address to which MacGroup or MacGroup-Digest is sent?

    If you change your e-mail address, just unsubscribe from your current one and subscribe under your new address.

  3. How do I subscribe to MacGroup or MacGroup-Digest?

    Go to the list information page at
    http://www.math.louisville.edu/mailman/listinfo/macgroup
    and fill in the form. The option to subscribe is near the top.

    If you change your e-mail address, please remember to unsubscribe from your old one and subscribe under your new address.

  4. What's the difference between MacGroup and MacGroup Digest?

    Both have the same content. Subscribers to MacGroup get the messages one at a time, as they are sent. Subscribers to MacGroup Digest get all the messages since the previous digest as one long message. The digests are generated whenever the queued messages exceed 80K bytes, or at 5:15 p.m. daily, whichever comes first.

    The digested version of the list is still somewhat experimental. Because of the dozens of different combinations of character sets and formatting regularly used in e-mail, it's no easy job to cleanly concatenate the messages when the digest is created. Many lists solve the problem by requiring all posters to adhere to a strict set of rules. We're trying a different approach; we're developing a program to parse the various formats into a common form. For this reason, you'll occasionally see unexpected formatting problems on the digest as we experiment with different ways to mangle the messages posted to MacGroup into a form suitable for MacGroup Digest. You can help when you see a possible formatting error by calling it to our attention.

  5. How do I post messages to the lists?

    To post a message to the discussion lists, just send an ordinary email message to macgroup@erdos.math.louisville.edu. This message will be automatically distributed to all 150+ subscribers. Only subscribers are allowed to post messages, so be sure to send the message from the same email address you use to receive messages from the list. If the return address on the message is not in the subscriber list, the message will be rejected.

    There is no moderation on the lists, so be careful what you post. When your message is sent, it will be immediately forwarded to all list subscribers.

    There are a few nuances to posting that are sometimes nuisances.

    First, the list management software, GNU Mailman, is set to look for certain key words in the subject of messages to avoid administrative commands being posted to the list. These include words such as subscribe and unsubscribe. Messages posted with these key words in the subject are likely to be rejected. Any line containing the string +++ will not appear in the digest.

    Second, only those subscribed to the list may post to the list. All other messages are rejected. The way GNU Mailman determines membership is from the sender's e-mail address. So, if you want to post to the list, you should probably send the message from the same account at which you receive mail from the list. (Or set your mail software to have an appropriate return address.) The reason for this requirement is to keep the spammers off the list.

  6. What kinds of messages can be posted to the list?

    Any message that concerns Macintosh computers and peripherals, including the iPhone and iPad. The connection can be quite tenuous. This includes computer items for sale and commercial events and seminars about such topics. Buying, selling and trading software is allowed, as long as the transaction is legal. When in doubt, ask first; the answer will probably be to go ahead and post it.

    The list is closed to general spam mail, and we have gone to some trouble in our efforts to keep spam off this list. We do not consider advertising for Mac-related products to be spam, in the context of the MacGroup list.

  7. What is the maximum size of a posting?

    Five megabytes. If you feel you need more room for a particular message, then contact the list administrator and make a case for it.

  8. I just posted to the list. Why did my message not appear?

    The usual reason for this is that the return address on your posting is not the account at which you are subscribed. Most of the time this happens because somebody subscribes with their home address and tries to post with their work address, or vice versa. To cut down on spammers, only list subscribers are allowed to post.

  9. Where is the archive of ancient messages?

    The message archives are hosted on a separate service: www.mail-archive.com/macgroup@erdos.math.louisville.edu/

  10. Will you give me a listing of all subscribers to the lists?

    No.

  11. Are the lists hosted on a Macintosh?

    Unfortunately, no, although they could easily be hosted on Mac OS X. The current hardware is an eight-core server with Itanium processors running Fedora Linux. The list management software is GNU Mailman, augmented by some custom Perl routines. If someone wants to donate a Macintosh on which to host MacGroup, we'll be happy to entertain that idea. Until then, we have better things to do with our Macs.
