I want to add a Facebook Group but it isn't in the list of groups

Currently, you must be the Administrator of a group in order to connect it.   

1.  Go to Facebook and Login as the Administrator of the Group.

2.  Confirm you have access to that group.

3.  Log into Socialdraft.

4.  Go to Setting | Social Profiles

5.  Connect the account.

You should now be able to post to that Facebook Group.
