There are 2 tags with the same purpose: Badge and Badges. I think badges should be used instead of badge since it includes one or many badges.
Thanks for the note :)
If the tag is only used once, you can just edit the question that uses it to use the more popular tag instead. I've just done that for this question.

You're right. Synonyms must of course be used for tag duplicates which are used regularly. For this one, just removing the tag was plenty good enough and saved some time. Sep 30, 2011 at 18:28
