The modes you can set yourself to require you to send an email to listar@linuxfromscratch.org. The modes themselves are set by writing the appropriate commands in the subject headers of the message. As the name implies the Set command tells you what to write to set a mode. The Unset command tells you what to write to unset a mode. Replace listname in the example subject headers with the listname to which you want to apply the mode to. If you want to set more than one mode (to the same list or multiple lists) with one email you can do so by writing junk in the subject header like "hello" and then put the commands in the body of the message instead. Set command: set listname digest Unset command: unset listname digest All lists have the digest mode available and you can set yourself to digest mode, after you subscribe to a list. Being in digest mode will cause you to stop receiving individual messages as they are posted to the list and instead you will receive one email daily containing all the messages posted to the list that day. There is a second digest mode called digest2. When you are set to this mode you will receive the daily digests but you will also continue to receive the individual messages to the lists are they are posted. To set yourself to this mode write digest2 instead of digest in the subject header. Set command: set listname vacation Unset command: unset listname vacation If you are going to be away for a while or wish to stop receiving messages from the lists but you don't want to unsubscribe you can set yourself to vacation mode. This has the same effect as unsubscribing yourself, but you don't have to go through the unsubscribe process and then later through the subscribe process again.
