Title: How do I create and manage "umbrella" lists?

Question: I have several small lists that I want to subscribe to a single
large list. How can I do that and how will it work?

Answer:

There are some occasions where it is helpful to have multiple lists
subscribed to a single "umbrella" list. For example, the professor of a
large lecture class may want to have individual lists for each of the
individual sections of his class but also have a single list for the
entire class. Rather than maintaining separate memberships for both the
large lecture lists as well as the individual section lists, it is easier
to make the lecture list an "umbrella" list.

"Umbrella" lists have other lists as their subscribers rather than
individual people. To create one, create a list as you normally would by
requesting one at

	http://www.washington.edu/computing/forms/mailman/

Once the list is created, subscribe the "sub" lists to it. For example,
let's say you want an "umbrella" list called "weave101" for your basket
weaving class and that you already have the following section lists
created:

weave_aa
weave_ab
weave_ac

The section lists should all have individual people as the subscribers.
The weave101 list, however, will have the following subscribers:

weave_aa@u.washington.edu
weave_ab@u.washington.edu
weave_ac@u.washington.edu

You'll want to configure the weave101 list to send password reminders to
the "-owner" address rather than individual subscribers.  This setting can
be found on the list's administration page at:

	http://mailman.u.washington.edu/mailman/admin/listname

where "listname" is replaced with the actual name of your list. In
this example, the URL would be:

	http://mailman.u.washington.edu/mailman/admin/weave101

To access this page, you will need to log in with your UW NetID.

In the "General Options" section, look for the "umbrella_list" option and
set it to "Yes."

One thing to note is that if a single subscriber is subscribed to more
than one of the "sub" lists, they will receive multiple copies of any
messages posted to the "umbrella" list.  They will need to use a local
mail filter to avoid multiple copies of the same post.
