The other downside is that releasing an update becomes a major nightmare. I
wish I had gone to serial numbers from the beginning but it's too late for
that now. *slightly biased PGHQ plug* - if you ask PGHQ to send an update
to all users who registered through them this becomes much easier and
they're very good about doing so....
