Idea for votes and publications

I have an idea and I want to discuss it with you before implementing it on CheckiO.

1. I want to give users only with the 3rd level and up an opportunity to vote. Before you reach the 3rd level you can’t vote for publications, comments, posts

2. I want to bring back dislikes on CheckiO. But you can’t dislike a publication without writing a comment to it. And you can’t dislike publication if it has 0 points.

3. The higher is the user level the more votes he can leave for a publication per one time. For example 3rd level user can add +1 to a publication, 8th level user +2, 12th level user +3 and 16th level user +4
