When you create a new mailing list, you have the option of also turning it into a group. If you will want your list members to have permissions on your wiki, be sure to make it a group. If the group to which you want to give permissions is not on the drop-down groups menu, ask a member of that group to add you.
We are all members of all-lib, which is both a list and a group: Choosing "display list characteristics" for all-lib in the athena list management page tells us, in part:
Description: Libraries staff list - all staff
This list is a mailing list.
This list is a Group and its ID is: 28676
Case in point: dsg-lib was created as a list, but not a group - so when we first tried to give dsg-lib permissions in the DOME Selection Group wiki, we failed.
The IS&T wiki administrators are able to turn lists into groups, after which, permissions can be applied. Email the wiki administrators for help.
Exception: Because of the evolution of the Confluence Wiki service, several groups, including "all-lib," are named "confluence-groupname." If you can't find your group in the alphabet, look under "c".
If you don't see the group (not the same as a list!) that you want, ask a member of the group to add you to the group through Moira.
