Facebook Chat, while a useful tool for chat, can be a constant source of interruption from your social network activities. So, what do you do?
For users who wish to set Facebook Chat offline, the "Options" section allows users to block incoming IMs and a number of other settings.
Users who set Facebook Chat offline do not appear to their friends on the contacts list, even while browsing their accounts.
Users can also appear offline on Facebook Chat to individual friends, so you can continue to use the Facebook Chat client while avoiding people you do not want to IM with.
