Hi. I've been using flex for a while and I'm now at the stage where I'd like to be able to develop AIR apps. I wanted to do something simple to start with...eg. have an AIR app on a few friends desktops that lets users tick a box if they can make it to a poker game. Do I need to learn another language like PHP to do this or can it be done using just Flex? Other than the live docs and dev guide that come with flex are there other documentation/online info that can be recommended.
