Need help with writing to XML

Hey everyone,

I’ve got this really simple login system that is used for about ten peeps.
But now I want these people, once they logged in, to write a short story, which has to be saved in an XML file. Can someone help me with this, really don’t know how to get it to work.

If you look at the flash file, and login using username “a” and password “b”, you get to the write screen. General idea is that when people write something here, and press the sned button… this info will be saved in the supplied .xml file before the other inputs

Thanx, Jellybean
