Numerous colleges and companies nowadays block access to Facebook.
This means not only can you not access the Facebook website, but you can't
even chat  with your friends using Facebook chat.
This is where CHIT CHAT(http:www.chitchat.org.uk) comes into play.
It is a free standalone Facebook chat software that allows you to chat with Facebook friends
without the need of the browser and even if www.facebook.com has been  blocked.
Please note that you have to enter your vanity username from Facebook and your account password to log into Facebook chat using this software.

So, if such is the condition with you guys, just give it a go.
Have fun................
