A very few options and settings can be changed only by them. Most any type of configuration change to a list may be made by the list owner. The listserv address is a machine running the list software, and the listman address goes to the machines administrators. The list's name both identifies the list to its subscribers and makes up part of its e-mail address. As an identifier to the subscribers, the name should be as short as possible while still being descriptive.
Many people use -l at the end of the name so it is easily identified as a list.
You have several options for the kind of list you can set up. These options directly affect how much work you'll have to do to maintain the list and also the amount of traffic your list will have. You may combine most of the following options. On closed lists, the owner must approve all subscription requests. On a public list, anyone who sends a subscribe message for your list is added to the list automatically.
