Actually, I was thinking that myself... lol
Mystery Man clone has been very clever to leave a trail of
Italics and
bold print... sometimes enlarged.
On top of all that he/she inserted a number of dots after several statements... something I do a lot...
He /she also like emoticons...
But alas, it's not me.
I still think its Kiwi but seeing that Mystery Mouth has yet to deny or confirm any of the most recent guesses, I have to assume that he /she is either playing silly buggers or we haven't guessed correctly yet.
