Here is how you get started

1. Log in with your facebook account

2. Everything works on a group basis, so you won't be very visible until you are part of a group. So, click on my group and create your group

3. Now, you should see on the left a "group key" that you can give to others to invite them to your group

4. Once you have 2 or more group members, you can post on the wall, and your group will show up in the leaderboards section.
