Flash Scratch to SL - Your Scripting Tool

Script ImageNeed to write a LSL script and don't know how to script?  I know I hate trying to get my head around LSLS when I an in a time crunch. So why not give Flash Scratch a try! Its a great tool for learning and scoding your own scripts for Second Life without having to pay someone to do it and without a crash course in LSL

A Huge thanks to John Bennet of ATLAS Institute at University of Colorado and Eric Rosenbaum at MIT for writing Scratch for SL to begin with.
