"Create your Library PIN/Password" Tutorial
This is, of course, confusing, especially given the recent password changes. To help eliminate some of this confusion, I've created a guide to creating a Library PIN/Password. (Why is it a PIN/Password? I think it started as a number (Personal Identification Number), but there are no character restrictions on it currently, so technically it's a password. Most of the instructions still call it a PIN, however.)
The following guide has text instructions at the bottom, and a screencast showing the process step-by-step. The video requires the Macromedia Flash Player.
Technical details: This screencast was produced with Wink, which captures screenshots and cursor movements, then assembles them with text annotations into a Flash file. Wink is freeware, and while it doesn't have some of the advanced features (like audio) of Captivate, Viewlet, or Camtasia, you can't beat the price! And it is remarkably good at what it does. I actually gave up using RoboDemo (the precursor to Captivate) in favor of Wink, because all I wanted was a simple screencapture-to-Flash-movie process. I can recommend Wink as a great place to start if you want to try screencasting.
