Welcome to the forums! I hope you and your daughter have lots of fun with ArtRage.
Sorry to jump on this post with a technical note, but here's a couple of things you'll probably find handy
It will definitely be worthwhile updating ArtRage to the latest version when you first install it ( either via "check for updates" in the Help menu or by downloading the latest installer from www.artrage.com/artrageinstaller.html )
This will give you Artrage 2.5 which has a bunch of new features including stencils and other fun stuff.
The registration key for ArtRage is printed on the plastic sleeve which the CD comes in, and is called a "serial number" on the packaging, which can sometimes trip people up.
If you have any error messages when starting the latest version of ArtRage which tell you that the tablet can't be found, downloading Wacom's latest tablet drivers from their website at www.wacom.com will correct this for you.
