Receiving data from another site
<p>I want to make a little web page which calculates stuff, based on various data from another site. Let's say for an online browser game.</p>

<p>I would like to have it take some specific details from the web pages on the game, but I don't even know where to start.</p>

<p>Is this doable with javascript (if not I would like to know with what language it is)? Could anyone give me a general of guideline of how this can be done?</p>
