New user-Discobot broken?

Hi all,

I am a new user of OmniFocus Forum. I have wanted to be a "good citizen"and learn the general way to use the forum before posting. I started in with the “Discobot” tool which invited me to learn, but after a few pointers Discobot seemed to behave as if it could no longer “hear” me. I would like to go through the complete Discobot exercise, and also know how to access it any time to refresh myself on any points. Any solutions appreciated.
