I just received my first "Tag" Badge (Microsoft-Excel, yeah!). When I looked into the Tags that had badges, I didn't notice any particular system for which Tags had Badges (at any level).
Are these Badges automatically created by the system once someone meets the minimum criteria (e.g. 100 upvotes and 20 answers for Bronze) for a particular tag? Or are these pre-set and only the current Badges will be awarded? I couldn't find anything in the FAQ or on Meta that addresses them.
