2 letters. Easy to type. should've made it lower case. I type all day at work. ALL our records go in an abominably programmed minimal support State computor system. It goes down often. Usually after I've typed a long entry on an important patient encounter - but just before I've done the equivalent of "save to the hard drive." I HATE typing; So initials are ok. Nothing more than "Buzz" is longer...

Cheers, BK (who should be "bk")
