It's not atypical. Send a geekmail to 'cscottk' (he's the admin in charge of microbadges) that you've been waiting 2+ weeks and he'll get around to approving them.
Hey all. I had a question and wasn't sure about the timeline of microbadge submission. According to the Microbadge Design and Submission
wiki, it can take broad range of time for badges to be approved or denied. Is there a general consensus on how long this process normally
takes? It seems like there's a not insignificant backlog, and some of the badges have been waiting for more than 2 weeks. I know it can take a while, but I was wondering if people with more experience would have insight into about how long to expect.
