I can only imagine. But hey they extended the submission date by a day, maybe they are extending the same courtesy to the voters as they did to us artists.
Doubt it; they only did that because too many people were trying to upload to the server that it created a bottleneck and people started to have trouble uploading their entries (which is why it’s always safer to finish before the deadline).
As far as the announcements, Mibus told me once that you shouldn’t expect to hear anything till February 14th - the day they announce the entire list of winners (Grand Prize, Runner-ups, Honorable Mentions, etc.).
