When I tried to add an activity in the Meal Plans and Scheduled Activities part of the event, the choice list for Activity Type was empty.  Why?

You need to define the types of activities you wish to include in your plans.  To do this select Activity Types from the Site Configuration menu.

Is it possible to set up recurring events for things like meetings?

Not in the same way that you can schedule recurring meetings in Microsoft Outlook, but you can do the next best thing:  you can create a "template" event and copy it forward in time using the Copy An Event function.

Can we make the Group Calendar available to the public without logging on?

When we asked our customers whether the Calendar should be made available to the public, we received some responses in favor and others opposed.   However, the groups that were opposed provided some very compelling reasons for keeping the calendar private, and we decided to respect their wishes.

We are concerned that providing detailed information about the times and locations of our customers' events to all unauthorized viewers could potentially create risks to their groups' safety. The security of your group's members is our foremost concern, and the secure environment we provide allows them to feel comforable about putting their information online.
