Just have received this via the O’Reilly UG news:
Calling All Flex Developers!
Are you doing any development work (including skinning and UI design) with Adobe Flex? Here’s your chance to be a contributor to an Adobe Developer Library book to be published in 2008, “Flex 3 Cookbook.” Adobe’s got a terrific site for Flex developers of any stripe to show their best stuff, and O’Reilly and Adobe are partnering on a book that will include some of the best contributions from the site. Each contribution uses the classic O’Reilly cookbook “Problem/Solution/Explanation” format; if you’ve got strong material to show the rest of the world, it couldn’t be easier to write up your material in the online fields, and join the cookbook party. Flex developers are in very short supply in an exploding market, so here’s your chance to show your stuff to the rest of the community!
So, if you’re interested and have stuff to show, throw it in there and it might end up in the book.
