Welcome to "Depress Me" - This is a little project I wrote to see how much money I was wasting on certain things, it expanded from there with other people from different banks wanting to know as well.
If you have online banking, go to your banks website, download your transactions in a csv file, and then upload it here, and this script will work it out! If you think it's dodgy, then don't do it, otherwise check depress.phps to see how it all works.. :)
