From Facebook Developer Wiki

I wish to point out an improvement that could be made to this project that would help the users across the board. http://www.facebook.com/help/question.php?id=893 Facebook Chat is fabulous, but I believe it could be much improved if the developers implement an option to block specific people from the user's Chat; either by being "hidden" from that person or the person being unable to access their chat window.

[edit] I have a problem with applicazione

I want to create a game but i see this

I'm not sure what you're asking for, since nothing appears on that link, so I suggest you use the Developer Forum and ask your questions there. Pete -- 563683308 11:23, 16 November 2009 (PST)
