What can be done to make the tag synonyms approval process more visible?
If you go to the tag synonym page you'll notice that a synonym proposal by Nick Carver from Nov 2010 still doesn't have any votes (well, I just voted).
I posted a suggestion about making that page more visible hoping that will get more traffic, but that may not be enough.
I do like Alex Lockwood's suggestion about adding the voting directly on the tag page, but still may not be enough.
