Help me answer a question that came up today; why is mIRC called mIRC; specifically, why the "m?"

Current guesses are it's related to Mardam-Bey, or because it's a Microsoft Windows client.

Anyone know the real answer?

Well you might find some conjecture around but I found this in the personal faq section on the site.

Question: What does the 'm' in mIRC stand for?
Answer: It quite possibly stands for 'moo', or perhaps even MU.

So it seems either khaled doesn't know or won't give a firm answer. lol

If Khaled doesn't know, who would? I think he's said several times that it's moo or mu. I still vote for Mardam-Bey.

I've always thought that a funny approach (even tho it's most likely wrong, and I dont care :P) was that the m stood for "my" making the program pronounced "my are sea"

My crazy theories:

'em eye are sea'
'em eye are see'
'mega'
'micro' (2.1a is rather small/simple if you ever try it (do note that it will crash when you join channels because some networks/IRCd's don't a ":" in the /names, this also goes for really old copies of mIRC))
