Dynamically saving/loading movie clip values

Hi folks

I could use some advice, I’ve been using Flash for ages but haven’t a clue about backend scripting.

I’ve got a flash app where you can add movieclips to the stage and drag them around etc…

…what I’d like is for the user to dynamically save the _x, _y and _rotation values so they can be viewed by other people.

What would be the best way to do this - write to an XML file or to a MySQL database? I’ve looked at some tutorials but its beyond my capabilities to be honest. Any pointers would be appreciated.
