Well, I don't have a fixed pattern.
Sometimes, I use my real name. Often I use names from Indian(Hindu) Mythology. Lately, (as on this board)I've begun using letters from my name or simply my initials.
I don't think I have a problem in disclosing my real name. My e-mail address is revealing enough

Maybe, it's a tad difficult to pronounce and remember
