When I asked this question: Using scoreboard objectives as arguments for commands, I created the tag minecraft-commands, since I thought that such a tag would be useful now and in the future (especially since the Minecraft command system has received significant upgrades recently).
However, the tag was removed from my post twice. What should I have done to introduce this tag?
Note that I have suggested a tag wiki for it, and I was notified that it has been approved, though I don't see it on the info page yet.
