Family Mint

Family Mint is a web based money appreciation program. It's "a mixture between a personal money management tool and an online bank." From their website...

Kids manage their money by setting goals and entering transactions.

Parents motivate through interest rates they set, ...automated allowances... and matching deposits. It's a fun system that makes it easy to see... where money came from, how much they have... and what they want to use it for.

So basically, if children earn an allowance, receive gifts of money, or have money through other means, you can enter their totals into your Family Mint family bank. Then as they use money, you can track it together through the parent and kid interfaces.

I think the concept is a good idea. However, money really doesn't exchange hands around here. We haven't gotten much use out of the Family Mint program thus far. I can see how it might work should my children ever handle their own money and need to learn to manage it.
