Adding permissions to a group that was created without permissions

If you have created a group in SharePoint 2010 and did not assign it permission at the time of creation, the following steps will allow you to add permissions.

1. Site Actions >> Site Permissions
   1. 
2. On the ribbon, select Grant Permissions (Note: your group will not be visible in this list of groups)
   1. 
3. Enter your group in the Select Users box (ex: Tony_Readers)
   1. 
4. Click the “Check Names” button
   1. 
5. In Grant Permissions, select "Grant user permissions directly" and select the permission(s) you wish to grant the group.
   1. 
6. Click Ok

When the list refreshed, you will now see your group in the list of groups and it will have permissions.
