E-mail notifications for user group

My questions has to do with e-mail notifications. We use EasyDiscuss as a support forum for volunteers for our non-profit. This isn't open to the public and is viewable only by our volunteers. I believe this feature exists but I am unable to locate it. I would like for everyone who is listed under a usergroup to automatically receive e-mail notifications of any new posts in the forum. This is the way we keep all members updated and on the same page. We regularly add and remove volunteers from the group so it changes somewhat regularly. Can users within a certain user group automatically be subscribed to receive e-mail notifications?
