* Non-logged in site visitors cannot view posts if groups were selected for the forum they belong to. |
| 5 |
* A user cannot view a post if their group role has not been selected in the meta box on the edit forum screen in the dashboard. |
| 6 |
* If no groups were selected, all users and site visitors |

* There are exceptions to this rule though. The post author, and users that have the ability to edit the post can always |
