|        2 | forum.view            |
|        3 | discussion.editOwn    |
|        3 | discussion.reply      |
|        3 | forum.startDiscussion |
|        3 | post.editOwn          |
|        4 | discussion.delete     |
|        4 | discussion.edit       |
|        4 | post.delete           |
|        4 | post.edit             |
