Both gamercat and gamer_cat cannot be changed to a character tag due to some permission locks set in place. At least one of these should be a character tag, obviously (the first tag is the official spelling, FYI). On top of that, I think neither are the best possible copyright tag. The official site name and the URL of gamercat is "The GaMERCat", so the copyright tag should be the_gamercat. But I don't want to add another third copyright tag until the two existing ones are rectified.
