Flash help. flash post text file

i had a idea for a site, and hell it could be also used in a sig.:slight_smile:

where there is a open space for writeing. some one presses submit boom its saved to a text file. and then everyone can read it. but the cool thing is any one can change the text just like that as fast as they want.:slight_smile: so basicly i wanna know how to make flash write to a text file.

also. i am a noob to hell when it comes to flash.

if anyone wants to make a fast thing of this:) i whould be soo happy!
