Frankly, we have several three letter initialed folk here, and I’ll scramble’em up sometimes. So it might work out better in the long run if you chose a name we could focus on (or remember) more easily.
I’m not thrilled with mine, but not disappointed enough to change it (it has almost no meaning with respect to me - I like a lot of Beatles’ tunes, but I hold them in equal esteem with Patsy Cline, Zappa, Wagner and Zep).
So, I’d guess I’d say that something a bit more memorable wouldn’t hurt, but don’t fray your synapses looking for something with deep meaning. And if you keep cookies turned off, as I do, keep it fairly short (you’ll get tired of typing a long one).
