Here is a FREE download of "The Actor's Audition Tracker" spreadsheet for you. You don't have to fill out every category for every audition. The most important info to track in my opinion is the project and casting director. The other info is really useful also, but if it's too much to deal with to log that's fine. If you know the project name and casting you can always search your email for the other info if you need it in a pinch.
