There's one drawback with this method: it's difficult to track down these custom e-mail overrides and each one must also be deactivated one by one. We receive many member support requests because they turn on this action and don't know how to turn it off or figure out why they are still getting notifications even after they turned them off via their preferences!
It's more efficient to follow every person, place (space) and content item you would like to follow and then choose to receive e-mail notifications for everything you are following in your preferences:
- http://scn.sap.com/user-preferences!input.jspa
- People, places and content I'm following (Followed Activity) = All activity
Also note that you can filter content, people and place (spaces) by those you are following and select to un-follow them from these lists.
