If anyone’s interested, they are testing the application process – you can visit this page for more details; but basically you find a badge you want, for example this one, read the Badge Requirements section, click Apply, fill in the “What qualifies you to earn this badge?” field (I pretty much just copied the requirements and wrote something to each point) and click “Submit”.
Even if you’re not interested in credentials or a Mozilla supporter, this seems kind of fun way to get some appreciation for all the work you, as a professional or an aspiring web developer, did for free with your side projects.
Either way, thanks for your attention and have a great day!
Also, here is my Webmaker profile with the badges I earned myself.
* Actually there is a small bug, so the badges are not quite transferable yet, but experts are working on fixing it.
