Information on your group site can be shared with other users, or kept completely private so that only you can view it. You have complete control!

By default, only your share page is publicly accessible and all of your information is private until you use the Share With controls to grant visiting rights to others.

You can share only a few items or documents, or you can share entire folders at a time. When your friends visit you, they will be shown only those items to which you have granted them access.

If you are comfortable sharing the group site with the whole world, you can choose the pre-defined "Public" group and set your sharing to this group. Then any one can visit and view the information, even without logging into KeepandShare to authenticate their identity.
