Select all facebook friends.
Do you want to invite all your facebook friends and you are bored to select them one by one?
Now you can use Facebook Select All to do this with just one click!
For best results, slide the sidebar of the open window where you select your friends until you reach the end of the list. This is needed for the browser to load the whole friends' list.
Spam more comfortably! :P
