Here’s a facebook hack that’s actually proven very useful to me in the past. One thing that I find annoying about facebook is that you can’t retrieve chat history if your buddy is offline… well now you can!
Click onto your friend’s profile page and copy their facebook ID from the address bar; i.e. the number after “id=”, highlighted in red below:
It might look slightly different, perhaps like this:
http://www.facebook.com/home.php#/profile.php?id=123132132213&ref=nf
But the important thing is to copy the number of the user, in our case 123132132213
Then while you’re still on facebook, type this into the address bar:
javascript:buddyList.itemOnClick(123132132213);
(with the correct ID of course)
And their chat window will pop up, saying “Jimbo is offline”. And if there’s any chat history, it will be displayed. How neat is that!
You can even open a chat window to yourself by pasting your own ID into the javascript, as seen to the right. You can use it for little notes to yourself, but remember that facebook chat history is cleared every few days, so don’t rely on it.
UPDATE1: A few people have had trouble pasting it in correctly, so here’s how it should look:
