I need a visual way to organise us all so we can quickly see if someone has something on a certain date so we ( and by we I mean DH) don't double book or claim ignorance.

Are there any good family calamders/planners/organisers? Ideally something that can gonon the fridge or be hung somewhere prominant rather than a diary ( though that would be good for me - I think Bathsheba mentioned a goo one some time ago)
