From Moneytrackin' help
To register a new user go to the signup page (https://www.moneytrackin.com/signup) and fill in the form as shown below:
The username must be an alphanumeric string up to 15 characters. Then you have to enter the same password twice (on Password and Repeat password fields) to ensure you entered the correct one.
Email is required. Our legal department has advised us to ask for it, as we need a way to communicate important things like changes on the Terms and conditions and such.
The address you submit is not public and not accessible to spam bots, and it won't be used for any other purpose than giving notices from us.
If there are any errors on the signup process (e.g: the username is already chosen) you'll see an error message explainig the causes, otherwise you are a moneytrackin’ user.
