For some reason, I can no longer rate skins. I have Apprentice level, and am a current customer on the site. I was able to rate skins on both the old WC site, and the new one after I migrated my account. However, for the last two weeks (at least) I can no longer rate skins. When I mouse over the stars, it doesn't show up as linkable anymore. I normally use FireFox, but have also tried Internet Explorer, and the behaviour is the same.
I've been a reasonable critic, so I don't see any reason why I should have lost this access. Help?
