Sorry if I'm being dumb, first time trying to alias a tag.

I attempted to suggest an alias: thick_lips -> big_lips (seems to be the same thing)
But the form says thick_lips is already aliased to something. thick_lips doesn't have a wiki page with an alias list, and posts with only thick_lips don't seem to show up in big_lips.

Again, sorry if it's meant to be a different tag or something I'm not catching!
