Is it just me, or is the "Rate This Simfile" button gone? I'm using Firefox, but I can't see it in IE either...
There are two reasons you cannot rate the simfiles. You either submitted them, of you haven't logged in, which you should be logged in. I'll check it and edit this post.
Edit: No problems with mine. I don't know what's wrong with yours. Are you using Internet Explorer 6.0 SP2?
All you have to do now is click on the rating. You don't have to click on the "Rate this Simfile" button. You will notice, once you click the rating, it will change what you rated them below and it should say thanks.
