off-list

Beyond the roster

Off-list describes communication sent privately rather than to a group mailing list or public forum: I'll reply off-list so we don't bore everyone.

The term comes from email lists, where members can choose between posting to all subscribers or contacting someone directly.

It implies discretion or a desire to take a conversation sidebar.
