The tags related to extending Visual Studio on SO are kind of a mess. There are way more vspackage questions than visual-studio-package so I just edited the 4 visual-studio-package questions to use vspackage instead. I tried proposing a synonym, but apparently I have insufficient tag score. Which surprised me a little, because I'm sure I've answered in one or the other of those tags, but ok.
Then I found that vsx which has almost 200 questions has a little cousin vs-extensibility with 47 questions. That's too many to hand-edit and bump. Again I tried with synonyms but no dice on the tag score.
So at least show me my tag score in the tag, so I know if I can suggest synonyms or not! Also, if I'm in the much-less used tag, chances are I won't have score there. Should I go to the more-used tag and propose the less-used as a synonym? I'm not sure what direction they work in.
