Everyone uses Facebook chat, but the problem with it is there is no option of selecting your own status except that of available and idle. So what can you do if you want to go invisible to a single person or a specific set of people whom you don't want to appear online. The reasons may wary from irritating relatives or your nosy teachers. So here is a simple, out of the box and a indigenous way of doing it within a few minutes.
2) Then select the big button that say Create a list.
3) Then a popup opens up with a list of all your friends. There, select a name for your list, and select all those whom you think should be in that list. After that confirm your selection by selecting Create list.
4) Then the last and the final step. Mouse-over the green button near the list you just created in the chat box and and it says "Go offline". So if you have to go offline to that person or that set of people in the group, just click on it to Go invisible!!
