Welcome to HBH! If you had an account on hellboundhacker.org you will need to reset your password using the Lost Password system before you will be able to login.
If you chmod 777...
Does that make a file world writable?
For example, say I chmod 777 index.php
And say it is located here: http://site.com/index.php
Then is the file world writable? Can I change it with a PHP script?
$file = fopen("http://site.com/index.php", "w");
fwrite($file, "AHAHAHAHA FUCK U NIGGER!!!!!!11!! DIS PAGE HAS BEEN H4X0RRREEDDDDD!!!!!!1ONE!!111!1!");
fclose($file);
I agree with moshbat, that is probably the dumbest question i've ever heard. If you are really to dumb to do this yourself, let me do it for you:

EDIT: not to mention how I think that php script deserves you to get warning points, but lucky for you im not an admin. :/
