Look at what's happened in this thread. The first PG to look at it couldn't pin down what was bothering him, so asked for someone else to look. The second said 'oh, I know which of us knows those canons' and paged him. The third offered a comprehensive assessment of the Permission request, drawing on that canon knowledge, offered constructive criticism, and then stuck around to address any queries about what he'd said.
This is wonderful (okay, I'm getting a little overenthusiastic here). This is what Permission Givers are supposed to do. :)
