This page demonstrates how you can use The Groups Place to manage your group. Although all settings have been made as public as possible for this group and its events, you can decide what the general public sees versus your members.... from the home page to what's visible for each event. You can even make your group completely private so that only people with a secret URL can find you.
Any event on this group are completely fictional, so feel free to sign up, comment, etc. to get a feel for how the site works.
