Budgeting
I may have mentioned this before, but I've been using Mint.com, a free online budgeting program. They have plenty of room for improvement but it's still very useful.
You have the option of email alerts for any credit card charges- when a card payment is due, and a weekly summery of your spending. It also keeps track of your net income, all your accounts including mortgage and tracks the value of your house and property to show net worth.
