FYI, this is something you can do yourself, for future reference. Simply prefix a tag with the following, where 'tag' is whatever tag you're trying to change:

char:tag for a character tag
art:tag for an artist tag
species:tag for a species tag
gen:tag for a general (white) tag
copy:tag for a copyright tag

Keep in mind though that simply changing a char/spec/copy/art tag into a general one is never a good idea; you really need to go through the tags like edidaf did and find those images that are legitimately using the fern tag for a character and change them to fern_character, then make the change. Otherwise you'll then have a bunch of images with Fern characters that need to be changed over, and it mucks up tag searches somewhat.
