I'm fine with moving them over - my experience last year was that it doesn't matter if you put them in that way or if the mods move them, it locks you out either way. (The other thing about the Marvel TV tag is that it does not show up under TV - I think it was generally showing up under Movies last year.)

I don't know what the tag with the dash will do, but if it doesn't lock me out and preferably shows up in the TV category, I'm all for it!
