This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
We would love to. However right now there would be no content in it, and we have found in the past that few people like posting in an empty forum - they feel that nobody will see their questions.
I would suggest that you start discussions in the Applications Frameworks forum, and when we can see that there is interest, then we can create a separate forum for Flex and move the topics to that forum.
