Wanted to create a synonym there but being a version synonym it's not possible for mortals. How are the policies about versions and softwares btw?
For the big ones we seem to like a single monolithic tag for the entire product (windows) and another tag for specific versions (windows-2008-r2). Same for the Linuxes out there. It gives the lazy an easy tag, allows the pedantic to cover all the bases, and allows people Interested in tags to just add one instead of an entire constellation.
Tag synonyms are odd. You need to meet some rep-requirements in-tag before you can suggest one, or enough rep overall (like 20K or better) to just do it to anything. In-tag rep is hard to get on SF outside of the big ones like linux or networking.
If you see one that needs a synonym and you aren't able to suggest one, a meta-post is just fine to get the discussion started.
