Nice site, but they require you to give them your credit card number to register, than after that, accept PayPal for further purchases. Why do they want your credit card number on file? Why not allow you to pay for your membership with PayPal? This is suspicious.
They also have many hidden cost such as goanimate character creator, which charges extra if you want to use all the features. After paying for a membership, most features come with an additional cost. Your child may run up extra costs or be frustrated in not being able to fully use the program. Its a great site, except that they seem to have a single goal of charging you every time you press a key on their program.
