A.: This is a FREE service! All you have to do is design your activity (subject, directions to be included...), read the instructions and  fill out the form. Then, if there are special graphic (page background, colour of links...) requirements, let me know what you wish your exercise to look like through e-mail.
In both cases you'll have to indicate what your e-mail address is. Please read our privacy policy for more information about this matter.
