The Mexican FMT was replaced by the new FMM back in 2010, the same year our site went into beta.
Since the old tag was only used twice and the tag wiki wasn't too detailed I just went ahead and made a new fmm tag.
I didn't add the
mexican- prefix since we don't have an
american- prefix on the tag esta or an
australian- prefix on the tag eta, and though other countries have a thing called a "tourist card" nobody else has an "FMM" so far as I'm aware.
