These differences make mailing lists more flexible than mail groups. Because mailing lists are more flexible than mail groups, a number of the SLS mail groups have been replaced by mailing lists. Other SLS mail groups have been deleted, as they are no longer useful. Since both mail groups and mailing lists are subject to spam, these lists cannot be promoted and published on the SLS Web site. Mail groups are maintained by SLS staff and have a self-evident list of members.
Mailing lists are dependent upon participants choosing to subscribe.
As with all email, error messages are generated periodically. If you receive one when using an SLS mail group or mailing list, check the SLS Designated Internet Liaison Manual, section B.5 to help decode it. SLS staff will investigate. Remember that sending email does not guarantee the intended recipient reads it immediately. While it works well most of the time, many things can happen along the way or at the other end to delay receipt.
