please help me to correct this sentence.

Hi,


We have talked to each other via microphone twice.


Is the sentence wrong? If so, how to correct it?

[Mister Micawber]

'Via microphone', though perhaps technically correct, is oddly phrased and very vague. Were you speaking across a stadium via the public address system? Were you on Skype? On your cellphones? All of those media use microphones.

The rest of your sentence is fine, but instead of 'microphone' use 'Skype' or whatever medium is correct.

Dear MM,


I chat with my friend through QQ.

I got what you meant. Thanks a lot.
