Mailing Lists vs Contact Groups
If you would like to create an SFU Maillist that allows other users to send messages to it, see instructions and usage guidelines on the Setting up Maillists.
As another option, you can create contact groups in SFU Connect (Contacts > click on small arrow beside the New button > New Contact Group). The Contact Group feature allows you to save a collection of email addresses. When you select a group contact while composing a message, everyone whose address is included in the group list is automatically added to the address field of the message.
