you can see that there not paying attention to you the whole time like they might stop talking that means their typing.
Chatting means to talk with someone.
You can't unless you are chatting with them. That is the only conversations you will see, the ones between you and them.
it means IdleSo how can a person actively chatting be "idle"?
No
Assuming you mean "can the person I'm chatting to online see me or can I see the person I'm chatting to?" The answer is sometimes. Many chat programs have the ability to integrate web cameras, or "web cams." Web cams allow the computer with the web cam to show its user to another person. If you want to see someone that person should have a web cam. If you want someone to see you, you need a web cam.
you cant
Yes
Some negative impacts for online chatting are: giving out too much personal information, chatting with people you do not know or do not know well, possibly chatting with someone who might cause you harm, etc.
Hehehe, there is no particular function for it, just walk up to someone and get chatting. See how it goes from there, send up hearts and stuff :)
Well, the only way it WOULDN'T be safe is if someone was reading over the person you're chatting with or your own shoulder, or if someone knew the password to either of your accounts.
You can tell if someone is chatting you up by the sound of their voice. Also by the questions they ask you. They also tend to keep a slouching posture and make eye contact with you.
