For me it doesn't matter...

I have a real name and people call me that way.

For flyertalkers it depends on what I remember at the time.

But I find it a sign of affection when folks like my BIG BRUDDAR PremEx call me "CATMAN" Or I'm called "Catbuddy," or "Cat" "Catdude" or "catty" (in a nice sense.)

Most people can't keep the real names and the handles straight.

I've only met one or two people who insist on their real name.

And you are right Mistah Love: there are too many DARN marc's and Marks out there.

TO keep me simple: call THIS MARK "CATMAN"
