Hello Mr. Bit, if you are really thinking of a moniker change I would definitely stay away from bit twiddler; bit basher might work, but I can imagine a few others like
the bitinator,
or the mondo superstyle bitbiter,
or this would be the best...bit bat baba nat smat cat trat flap it tat flip a dat bit bat.
I think the only problem I can see if you change your name is you might lose your post count, but do what you got to do.
Seriously, thanks for all you do to enlighten folks on this forum. As far as I can see you are in the top ten of knowledgeable and helpful types.
