Just how do I stop a person from seeing me on Facebook Chat?
Make a friend list of those you do not intend to see you on-line by clicking
Create New List.
(resource : insidefacebook.com)
You can after that relocate those people to the checklist by clicking
Add to List.
Chat in the lower left edge.
Then toggle the offline standing (environment-friendly toggle alongside the checklist name) of that certain close friend checklist.
