Somewhat seriously, I have another argument against using blackboard
bold fonts: I can't get them to work with jsMath. I think I have all
of the appropriate fonts installed, but when I try to view something
typeset in blackboard bold, I get the message "Unknown control
sequence '\msbm'." Does anyone have any advice?
