Edit Flow - can't see the calendar as administrator

Hi, I would love to use Edit flow (you have recommended it in one of blog posts), but somehow, even as an administrator I have no rights to see the page with calendar (and the forum is dead).

Could you help me how to fix it (reinstall the plugin did not help), or any other tool where which will add an approval possibility to the main editor? (anybody writes the post, and he will have to add an approval before publication/scheduling)?

Thanks a lot
