Family Notebook

How do you keep track of your family's important information? I have a family notebook. It is a binder (kind of like my coupon one) with page protectors. I keep information in it that I can never seem to find otherwise like phone numbers and medications. It is very handy! Has anyone tried an online record keeping system? I just came across this one and was wondering if anyone had tried it. It is free! Let me know what you think. *some links contain affiliate information.
