I think its more than 'British'. I am Pole and also feel like i should not vote for my piece in any contest. I introduce something for the people to vote, it is obvious that i want to win and i would vote for me, but that is not the point of contest. It is up to the people to judge if my work is worth beeing #1. To be honest i never saw any contest where participants were allow to vote... This forum is first exception, i adjusted to the rules, but still weird to me .
Of course i dont say this to make some people feel bad about it, so don't take it this way.
