The cool thing about the enzyme system is that options
for say school, company, concentration, etc are
populated dynamically as people use the site. You come
along and look for you school; if it isn't there, you
enter it, and then the next person from your school
doesn't have to enter. However, maybe the first person
from the school was a bad typist and speller, and the
second person wants to amend the previous entry. At
this point, she can't. It would be a cool feature to
have some system of managing updates to shared resources.
