I have a google group, and the discussion is slowly catching up. We use several tags for each post. Is there a way to let users subscribe ONLY to some tags.
Either directly through the google group setting, or by letting the email arrive with the tag listed, and then setting up a filter system on the mail program that only keeps unread messages with certain keywords.
I could not find ways to subscribe to a single tag, nor ways to add the tags in an email (to filter later).
