This one's on how to kill the logo in Damien Cassou's Web dev image, and a little miscellaneous stuff about getting started.
Target audience: people getting started with Squeak. All this actually does is give you a quick overview and show you how to remove the little logo Damien's image comes preloaded with. (I'm hoping/planning to do something a little more in-depth and useful soonish, but for now that's entirely vaporware.)
