If the votes are tied, the entry with the earlier entry message time will win.
An entry message’s time is the time it was posted, unless it’s been edited/updated, in which case the time of the last edit becomes the entry message’s time.
Also remember that when updating, you are required to give your new entry a new filename/URL. This serves two purposes. First, it means that there shouldn’t be any problems with old versions of the entry displayed from peoples’ web browser caches. And second, it means that the entry message must be updated to reflect the change in filename/URL, giving a more accurate time for the entry message.
Hopefully, this makes sense
Oh, and updates are permitted after entry submissions close, but they’ll be ignored for voting
