Ok I’ve made a simple frontend exclusion of the ratings stars for users that have already posted in a ratings topic.

Ideally, I’d like to modify the topic and/or post guardians on the server to prevent a user from posting in a ratings topic twice. However, with my limited ruby skills, I can’t see an easy way to do this without just overriding the existing methods (assuming that’s possible this isn’t a very sustainable thing to do)… any ideas/tips? @sam
