Among my various rejected edits, one particularly stood out: the now-synonymized sophont tag.
I was unable to suggest synonymization, so I did the next best thing: edit the tag to accurately reflect the term. I assume someone with privileges came along and synonymized it, and my edit got axed by the system in the process.
I don't think that the tag would have been synonymized without my intervention, and that's a problem. While I now realize that I could have either brought it up here on Meta, or in the site chat, being able to flag tags for review by more privileged users should probably be a feature. Alternatively, a way to propose synonymizations (and subsequently be reviewed) would solve the same problem.
EDIT: I re-read the relevant privilege. I still think the ceiling to synonymize should be lowered-and flagging tags for review still feels like a good idea.
