Both Brian and I are at DrupalCon 2008 in Boston this week. We will be giving our presentation about content-managed Flash and Flex sites with Drupal tomorrow night at 4:45 PM, but we’re both going to focus far more on the Drupal side of things and touch briefly on the ActionScript and Flash, so that even Flash and Flex neophytes will understand the entire backend, setup, and use cases.
If you would like to learn more about how to use the Flash / Flex stack, however, you have two options to get training from Developer Community Champions that we should mention.
