I came across ext and had to do a bit of research to discover that it's a JavaScript framework, with most of its questions tagged extjs. I tried to propose it as a synonym but discovered that there was a rep requirement within the affected tags. What's the right thing to do then?
There are about 100 questions in ext. I went through them all and retagged 3 or 4 that turned out to be about Linux file systems. The rest are unambiguously about the JS library. There are few enough that one could retag them all manually, and I started to do so, but then thought that such mass editing might be Frowned Upon, given that even suggesting it is something I'm apparently not trusted to without being knowledgeable enough to answer questions about the stuff.
Please advise. Should I undo my retagging edits?
