# Any method that returns a status code (0 for ok) can also send:
# return(-1,"message") <-- just puts up a dialogue
# return(-2,"message") <-- also asks the user to e-mail me
# return(-3,["type",v],id) <-- version conflict
# return(-4,"type",id) <-- object not found
# -5 indicates the method wasn't called (due to a previous error)
