A couple of errors.

Unless I'm the one that facilitates the vote change, all that can be done is to change the numbers. Chruser and I can remove the vote, but I'm the only one likely to go to the trouble. I had considered a hack that allows users to change their own vote, but I am unsure about it.

As for the server errors, I havn't encountered any in quite some months, so I wouldn't know where to start.

Just make the hack where they can only change once, that way it will be used for fixing errors and not flip flopping for the winner.

yeah, that would be very useful to me, and most likely all of zel members.
