Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers.
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.
