Just wanted to share a great piece of software I stumbled upon recently called "You Need A Budget" or "YNAB" for short:

It's more than software really...it's more of a methodology for personal finance/budgeting with accompanying software. The beauty, in my opinion, is in its simplicity. That and the common sense approach to stop living paycheck to paycheck.
If you happen to be looking for money management software, it's worth checking out.
