It can be a challenge getting everyone in a family to agree on what's for dinner so planning ahead gets the sting out of it. Once everyone has taken the time to sit down and help draft the weekly menu, the shopping list must be done. For both of these, menu and shopping list Organized Home offers simple and practical forms that can be downloaded free of charge, just visit their Printable Gallery to see what's available.
Besides these forms, they also offer a lot of practical advice such as getting organized, cutting clutter and once a month cooking (and freeze it).
I wrote about Maya's Mom recently in On the Parent Track and they share practical advice for parents.
As for scheduling appointments, planning work and events and other calendar activities, I started using Backpack which allows you to do that in your browser, on any computer, anytime, anywhere.
The account with an Online Calendar starts at $5.00 a month.
I learned about Organized Home on Lifehacker.
