What does this JS do?

<a href="http://pastebin.com/ceWGKZjJ" rel="nofollow">http://pastebin.com/ceWGKZjJ</a> , now you just need to firebug a Facebook page so you can figure out what those element IDs do...<p>At a quick glance, I'd say ErrantX is correct.

If it works like the others do: it sends a request to your friends to add the group/page etc. (this could be different, I haven't had a close look, but it is what others did)
