The search bar does not work! Answered
From the explore page (https://www.instructables.com/tag/type-id/) I tried to use the search bubble at the top right. I typed USB charger for example, and it takes me to a search page (https://www.instructables.com/tag/type-id/?sort=none&q=usb+charger) but that page only has a grey bar with the words "Let's make 'USB charger' with an option to choose different categories, e.g. everything, technology, etc... That page doesn't show any search results. It appears to be the main search page, because it has a little magnifying glass button after the text, but when I click it, it just returns me back to the "Explore" page cited above. I can't figure out how to search the site.
Also I tried to attach a screenshot but neither the new uploader nor the "old" uploader are responding to my clicks.
