Hi Maggie ! Karel has retired from active research. Retired being my word, not his. He sent a notice out to the list some months ago as to this effect. I believe he did mention that those he was doing research for, he would finish up. His proffession no longer allowing him the time to do Gen research. Regards, Mike in AZ SWARTZ~SVARC / CERNY / HAJEK / HOSEK / HRABAC / KREISSINGER / CERMAK / PERGLA
