Whats the correct way to ask someone how to find them on Twitter?

I was playing Trade Nations (mikeypants if your addicted like me) on my slate o'joy and was asked by another player, "are you on the twitter". I knew what she was asking but it seemed like an odd way to ask. So my question is, what is the correct way to ask someone how to address them on Twitter?

"What is your Twitter name?" "What is your Twitter handle?" "What is your Twame?" "Who do I follow to experience teh orsome LOLz??"
