As announced recently, Adobe is offering Flex Builder 2 with Charting free of charge to educational establishments and students. The link to register for your free download is now on the Adobe developer connection site, or you can access the registration site directly at http://www.flexregistration.com/
When registering you will need to provide proof of eligibility – so that means you’ll need to scan in a copy of your student ID or a letter on an educational institution letterhead stating that you are a current student. Once you’ve got that you’re good to go and get your free copy of Flex Builder.
