Plagues in Pre-European Americas? got me thinking. It has the tags south-america, central-america, and north-america. My thinking was that it would be much more efficient to have one consolidating tag for questions that require it. The obvious choice is americas. However, the tag america already exists, albeit it means something entirely different. I've proposed it be a synonym of united-states, but it has not yet been approved. I tried to create the tag americas, but the system obviously wouldn't let me do it because it thought it was just a synonym of america.
Is there any way a mod can override that, or must we delete the tag america?
