Adobe's Developer Connection has added Adobe Cookbooks, http://cookbooks.adobe.com/home.
Members can post Adobe code for Flash, Flex, Air, ColdFusion, Dreamweaver, and other Adobe products. At this point the majority of the code shared is ActionScript and Flex code. Anyone interested can browse the cookbooks and no registration required. If you are interested in contributing code and interacting with other members, then registration is required or log-in with your Adobe account if you already have one. The site has community moderators, who monitor and facilitate discussions and also have the ability to improve the content.
