I have always spelled it out m i r c
I guess merk is ok, but its like pronouncing IRC as "erk"
"Yes, I chat to people all over the world on erk"
just doesn't have that certain ring to it
- That's exactly how I'd say it (not that I ever have though to be honest, it's not something that comes up in conversation in my experience). Generally speaking if an acronym can be pronounced easily it will be, (eg. NASA, AWOL, RADAR, SONAR, ASAP, GIF, WAV).
