    knowing they will stay private and safe.
  •  Let everyone know when and where you’ll be,
    by adding your trip to the event calendar.

    knowing everyone who can view it can be trusted.
  •  Plus much, much more!
    We roll out new features every chance we get!
  •  Everything you add is completely private,
    so the rest of the internet doesn’t know it exists.

    and allow everyone in your group to participate.

As well as personal/family uses, Jabbster could be useful for parent/teacher/student/class communication and student learning networks.
