Hi
I am sorry if I sound kiddish.
Honestly I do not know much about JavaScript. Can someone tell me if it is possible write a script in JS to automaticaly complete sign ups on a website.

You could, if you knew the names of all the fields, write some JavaScript in something like Greasemonkey, to handle tasks for you automatically for certain websites. If you are totally new to JavaScript, we aren't going to be able to teach you how to do this in this thread alone, however.

thanks wow good answer
