Maestro comes from my musicianship - I am a pianist ... JJ are my initials, and P is the first letter of my french name in high school. LOL. Quite a long story, but there ya go.
I actually normally use just "Maestro" or something other than that but I've been adding on JJP lately... it's where you can find me on instant messenger.
The name everyone knows me as (even in real life), because of porn, is "PK" - for "Porn King" - but in the actual online realm of pornography, that name is obviously, already taken.
