The specifics of the study section are Forms. Forms are how, using html, I can get data *from* a website. Depending on what "controls" I use, I can get binary data (checkboxes), multiple-choice input from selection lists, text of some varieties, and passwords. Two interesting points are that each form requires a submit button, and that "password" does not actually encrypt the text; instead it simply makes it undisplayed but the password is passed to the server as simple ascii.
