 **Private Mentions**
 
-If you wish to restrict a post to a single person or a number of people, you can do this by selecting channels or collections from the privacy tool. You can also just tag them with a privacy tag. A privacy tag is a name preceded by the two characters @! - and in addition to tagging these channels, will also change the privacy permissions of the post to include them (and perhaps restrict the post from "everybody" if this was the default). You can have more than one privacy tag, for instance @!bob and @!linda will send the post only to Bob and Linda (in addition to any recipients you selected with the privacy selector - if any).

-You may also tag public collections. When you create or edit a collection, there is a checkbox to allow the group members to be seen by others. If this box is checked for a collection and you tag (for instance) @!Friends - the post will be restricted to the Friends collection. Check that the collection is public before doing this - as there is no way to take back a post except to delete it. The collection name will appear in the post and will alert members of that collection that they are members of it.
