From your email program, send a blank message to:
groupname-unsubscribe@yahoogroups.ca
Make sure to replace "groupname" with the actual name of the Group (e.g., poutine_lovers-subscribe@yahoogroups.ca).
Alternatively, you may wish to remain a member but reduce or eliminate Group email by changing your subscription option to No Mail/Web only or Daily Digest.
Note: If you moderate a Group, you can't unsubscribe from the Group on the My Groups page until you have appointed a new moderator.
