The server maintains several lists in order to conduct its business. You can use +/-/= to change and view the various lists.
Examples (using the aliases):
|+listname member||(Add member to listname - addlist)|
|-listname member||(Remove member from listname - sublist)|
|=listname||(View the members of listname)|
|=||(View the names of all lists and their status - showlist)|
Certain lists can only be modified by an admin. Other lists are for admin viewing only. See showlist help file for details.
