Flash content management

Hi all!

Somebody please refer me to a Flash content management tutorial.

All I wanna be able to do is have a login area for the client to be able to go into…and change a text that’s on the site…then alter it, add to it whatever…then hit a button that updates the front end of the site there and then for all to see!

Do I need a database?..PHP, ASP, XML?..whichever is easier would be good!

Is there a tutorial or sample for that?
