actually u have to have an ftp account with your host and stuff
if u dont want to use ftp then u could try creating a php script and sending it your highscore info such as
execute file("http://WEBSITE.net/script.php?200_MYNAME","","")
and you can enter a web address into it and it will start it in the default browser
script.php is the php script ? signals command line for the script 200 can eb the highscore _ is a seperator since i dont think commas work online MYNAME is the users name and using that and some php knowledge you could have it see if the score is more than everyone elses and generate a file called highscores.html and voila
dont ask me for any help on php as i dont know a lot on php
