Please have a quick look at this.
I found a way to implement an easy voting system directly on SP-Studio.de (wordpress). What do you think of this? Right now you need to click twice to exit the big view, but I think I will be able to fix this. I haven't edited it yet because I wanted to show it to you first.http://www.sp-studio.de/sp-studio-contest-vote/
It's really easy to use (for me and the voter) and works like Facebook, but you don't need a Facebook account. I noticed some of you did not upload pictures in the last contests and it might be because of the Facebook votes. So I hope this will be better. You can like as many pictures as you want and in the end the one with the most likes wins. This could be shown on the front page instead of a single page, but I have to make sure every picture has the same chance to get noticed.
I found another WordPress plugin which should be able to provide the star ratings
some of you are missing. But unfortunately this one would cost 30 $... So I am not sure it this is worth it. And I haven't found a demo for it, because the official demo does not show ratuings. I'd be willing to spend those 30 $ if I'd know for sure more people will use star ratings. But I don't even know yet if they want to vote at all. Perhaps I should try the one with the likes first to see how a vote directly on the website is accepted by the visitors? I don't want to change the system all the time, but right now we haven't found a good solution for the vote yet.
The upload still works great, this month I already got a nice amount of pictures. So I won't change anything there.
