Is Snowcone the only person who can make substantial changes to the site's design?
I'm thinking that maybe changing the Upload A Cover page, to add some information about submitting the cover to the forums for assessment before uploading, might help ease the situation? Or (preferably) restrict the Upload A Cover to only be accessible by registered forum users?
I think there's probably quite a lot of people who visit the site looking for covers - and also try to upload ones that are missing - without ever visiting the forums. So they aren't aware of the quality requirements or anything like that.
I'd be surprised if many, if indeed any, approved covers come from people who aren't forum users. So I don't think restricting uploads would cause any loss of covers, and might just make things a lot easier for you Cover Admins.
Never mind. Just opened TCP in another browser and realised you do need to login.
I still think some text suggesting people submit their cover to the forums for assessment first might just help the situation. Maybe even on a separate page before they can upload?
