Free FlexBuilder 2 and Flex Charting 2 for Students!!!
I found a nice offer by Adobe recently, when I was searching their web page. If you are a student you are allowed to download an use FlexBuilder 2 and Flex Charting 2 for free!
All you have to do is follow the link:
http://www.adobe.com/devnet/edu/index.html
Register yourself at adobe.com, upload your identification, that you are studying at a university and you will get your own license key in a few days.
I hope they will do that for Flexbuilder 3 , too.
