Are you on Facebook? Help me with English?

[Erik]

Hi

I speak English as a second language

When we ask someone about his/her use of Facebook(or Twitter), we go like

"Are you on Facebook?"

Q.1 what does "on" mean in this sentence?

Q.2 and what can i say if I want ask someone about his/her use of instant Messaging apps???

Can i go like "Are you on Whatsapp(or Viber)?"

or "Do you have Whtasapp?

Thank you again

You can go to Facebook and answer ?'s to get more proper English but could I suggest you get a tutor to help with your English? You can put an ad up at the local college. Good luck.

you should mention your language so that i can really help you.....
'On' means that when you are like.......i'm saying i'm lying on bed....
Well i do not know how to be more specific......if you tell your language then i might add you............
You add me on facebook....i will try to help there.....add me by looking at my email ID from here.........

Are you on facebook ?
In this, "on" means that are you using facebook ?

You can use both these sentence
Are you on Whatsapp(or Viber)?"

or "Do you have Whtasapp?

You can also use
" Do you use whatsapp/viber ?"
