We have a tag synonym that retags several tags, including downvotes, to down-votes, and the same is true for upvotes and up-votes.
downvotes, however, is the better tag because downvotes is more commonly used than down votes, and likewise, the same is true for upvotes.
downvotes - 1051 results vs. down votes - 499 results
upvotes - 1781 results vs.
up votes - 497 results
Wiktionary has entries for downvote and upvote, but none for "down vote" or "up vote".
And, um, even the tag wikis uses the one-word form.
Could we reverse these tag synonyms to the one-word form?
