A couple of readers have mentioned a new A5-size family calendar, so I had to check it out for myself. To find it at Filofax USA, click here, then scroll all the way to the bottom of the back and click Family Organizer Pack. (I assume it's available in the UK, too, but I wasn't able to find it on their Web site.)
When you click a new window opens listing everything that comes in the pack, plus an offer to get $10 off and free shipping on an A5 organizer. Presumably, the offer targets mothers who want the Family Pack but don't already have an A5 binder.
And the contents of the pack are yummy: Pages for school and sports info, shopping lists, emergency info, travel and party planning, budgeting, and (my favorite), a chore organizer! It also includes a 2009 week-per-2-pages calendar that has slots for different family members.
I can imagine you don't need to have a family to find this pack useful.
