I don't know if this idea has been discussed previously, but I was wondering about the possibility of being able to enter competitions twice... particularly useful if not many people enter a competition.
The way it could work is... if people enter twice, then if loads of people have entered by the time of the closing date, then their first entry only would be put up for voting. If not many people have entered, then maybe both entries could be up for voting.
I don't know whether people could see this as unfair, though.
It's probably a silly idea, actually...
