Create (or Delete) a Sub-Group

There may be times when you want to post to a subset of people in a group, and that subset does not by itself exist as a group.  For example, you may want to post to all senior history majors, but there is no “seniors majoring in history” group in the Timeline. You can request the creation of such a group, but it is easier and faster for you to create a sub-group of the seniors group that is restricted to history majors. That is what a sub-group is for. 

screenshot - sub-groupsA sub-group consists of a primary group (in this case, seniors) and one or more “restriction” groups which restrict which members of the primary group are also in the sub-group (in this case, “history majors”). Note that in this example, you could achieve the same outcome by using “history majors” as your primary group, and “seniors” as your restriction group.  In both cases, your sub-group would end up containing students who were both seniors AND history majors. 

Which way should you do it?  You should pick as your primary group a group over which you have posting rights. So, if you have posting rights to the history majors group, but not to the seniors group, pick history majors as your primary group. If you have posting rights to the seniors group, pick that as your primary group. If you have posting rights to both, pick either one. You do not need to have any rights on the restriction group(s), because your rights on the sub-group are exactly the same as your rights on the primary group.

To summarize:  A sub-group consists of a “primary group” (to which you must have posting rights) and one or more “restriction” groups which reduce membership in the sub-group to individuals who are in both the primary and in all of the restriction groups.  The primary and restriction groups are just regular Timeline groups – you cannot use a sub-group as a primary or restriction group.  Once created and named, sub-groups exist until you delete them.

To create a sub-group:

  1. Click the Publish tab
  2. Click on the My Groups sub-tab 
  3. Click on the orange +Create SubGroup button on the lower right side of the screen
  4. Enter a name for the sub-group (e.g., “Senior History Majors”)
  5. Select the primary group from the drop-down under Step 1:  Choose Group
  6. Check off one or more restriction groups by checking the box next to their names (if the restriction group you need is not listed, contact the Timeline administrator)
  7. Click Done

You should now see your sub-group listed under the My SubGroups banner.  You can use this sub-group as the target for any posts that you make.

To Delete a sub-group:

  1. Click the Publish tab.
  2. Click on the My Groups sub-tab.
  3. Click on the Delete button under Actions in the row corresponding to the sub-group.

To Edit a sub-group (change its primary or restriction group(s)):

  1. Click the Publish tab.
  2. Click on the My Groups sub-tab.
  3. Click on the Edit button under Actions in the row corresponding to the sub-group.
  4. Proceed as with step 5 above to create a sub-group.
