I saw this in many clubs and decide to make the contest here.
These are the rules:
1. A subject for the round is chosen by the winner of the round.
If the winner doesn't pick (or doesn't want to pick) I'll pick the next subject.
2. Everyone has 3 days to submit their icons here.
-YOU MUST MAKE ICONS YOURSELF!
- No stealing icons!
- Only new icons!
- Size 100x100
- One fan can add only one icon
3. A pick will go up for voting.
- There will be 3 days for voting
- Don't vote for yourself!
4. There will be the points for winners:
3 for 1st place
2 for 2nd place
1 for 3rd place.
So we'll have the winner of the contest in the end.
5.There will be the props for winners:
3 for 1st place
2 for 2nd place
1 for 3rd place.
