In order to simplify the tedious task of entering your classes one by one, I've taken the liberty of creating this lovely little interface for you to be lazy and paste your class info directly from the revered Penn InTouch. All you need to do is copy the text class descriptions from Penn InTouch (you'll find them right below the pitiful representation of a blocked schedule), and paste them below. Mash the button, and you'll arrive at the Schedule Maker main entry form, but with all your classes already filled in!
Currently, if you want to change the colors of your classes, you'll have to do some reading in the release notes, specifically the sections on input format and styles. You'll also have to know a tiny bit about style sheets. It's really not that hard -- drop me a line if you're having trouble. (Besides, realistically speaking, if you're going to define colors for each class, you might as well enter them yourself -- you're not saving much time by not doing so :P)
And so, without further ado...
