I am trying to write an application for website powered by drupal, basically i would like to create an application only authenticated users are able to use, and users are only allowed to connect with members of the opposite group they are a member of. I have been learning flash builder 4 and learning the basics of actionscript but I am still pretty new to Flash and Flex development. I would like to users to connect using the Adobe Stratus 2 protocol and if possible by authentication on existing site and using membership data from existing mysql database. If anyone could give me a nudge in the right direction on how I should go about creating this application or the next steps i should take, it would be greatly appreciated.
