With the exception of my initial formatting problem on my resume, it is super-easy to apply online.
You open up each school's application, and it is basically filled out for you from the common info form. Then you get to attach you resume, PS, and whatever else. It does not require any amount of technical savvy. It is esentially the same as putting an attachment on an email. Then it shows you how your document will print out for the law school people.
The final step is to transmit...the beauty is no post office lines.
