However, what exactly can be done for those questions?
For example, the two oldest questions on the site are both untagged and are both asking for rules clarifications:
Presumably, these questions once had game-specific tags which have since been auto pruned.
If the untagged tag is a bad thing
Is it desirable for users that can create tags to recreate the game specific tags?
Or, is the intention that these questions remain untagged for as long as there is only one question per unpopular* game and then the tag should be recreated?
If the untagged tag is not a bad thing
But rather entirely valid, should the description of the tag be changed to remove the part about requiring editing and perhaps state that some questions are expected to be untagged.
Should the requirement for at least one tag be lifted for this site?
