Following up on my earlier comment: I've added a number of popular synonyms for the most used taxonomy terms on 43 Folders. For example "OS X" and "Leopard" are synonyms for my preferred "Mac OS X" term.

Is there a Drupal module or the like that can redirect taxonomy pages for synonyms to the page of the preferred term? E.G., I'd love for visits to "/topics/os-x" to do a 301 redirect to the preferred "/topics/mac-os-x" page.

My thinking is that if a contributor enters "OS X" as a term for a new node, it would still show up by "Posted In:" as "OS X" — but clicking the term's link would take the visitor to the "/topics/mac-os-x" page. Seems like this gives contributors the ability (within reason) to tag things with what makes sense to them, but it lets me (the site owner) retain a certain amount of control over the vocabulary that minimizes sprawl and ensures visitors can find what they want without leakage or unnecessary hunting.
