Question: How do you pronounce mIRC?
Answer: I pronounce each letter, m-I-R-C. However, it's fine to pronounce it as 'mirk'. Often during a conversation I'll switch between both pronunciations, depending on how quickly I want to get my point across!
Question: What does the 'm' in mIRC stand for?
Answer: It quite possibly stands for 'moo', or perhaps even
MU.
