Notices means you'll only get announcments sent to the excs-notices list address at survex.com. This list is much quieter, but you'll miss out on lots of fascinating chit-chat. Discussion means you get a copy of everything anyone sends. Notices are also sent to the discussion list so you only need join one of the 2 lists.
You can also choose to receive a digest version of either list this means that instead of getting lots of individual messages, you'll get at most one message per day which contains several messages within it (actually, there's a size threshold in the list software, so if the list is very busy you may occasionally get 2 or more digests per day). You can take a digest of the notices list, but there's not a great deal of point - it's very uncommon for this list to get two messages in the same day.
You can choose a text or MIME version of the digest. If you have clever mail software, the MIME version may present it to you as a collection of messages in some nice way. If not, you may prefer the text version (which is the default).
The simplest way to join the list is by using these links:
If you don't have web access, you can join and leave the list just by sending e-mail (for example, you might want to tell a friend with e-mail but no web access how to join). For instructions, send a message with help in the subject to listname-request@survex.com
(replacing listname with excs,
or excs-notices as appropriate).
Or if you'd prefer to unsubscribe entirely, again use the methods described above.
Or it could just be quiet at the moment.
Do not mail the list to ask -- it's a waste of everyone's time, and of bandwidth. The best approach is to try to subscribe as described above. This will tell you if you're already on or resubscribe you if you aren't.
You'll also want to change your details on the on-line address list. It's best to unsubscribe before leaving - it saves the list from having to send lots of messages which will never get read.
