Documentation is limited and I think I have some problems due to hosting with MySQL 4.0.x. But after some manually table creation and data insertion I could start using the component.
Looks (wooden board) a bid old fashion style. Doesn't fit the modern/design look of many templates.
Good: because it is fun, nice functionality (postit, pictures, youtube), it works, has may configuration parameters.
Not excellent: lacking documentation, doesn't work 100% in my situation.
