- Are comic-identification questions on-topic? (I asked one, and created a tag for it - should it be tagged story-identification?)
- When tagging comics, should we have a tag for the writer and a tag for the illustrator and a tag for the title? (What I did when tagging.)
- Story identification questions are on-topic, and comics are on-topic, so comic identification questions should certainly be on-topic. I would, however, tag them with story-identification rather than creating a new comic identification tag. The skills required to identify a comic are much the same as those required to identify any other kind of story, so it makes sense to group all these identification requests together under a single tag.
Personally, I only use the author tag I see most relevant. E.g. when asking about the story, I use the writer tag. When asking about the art, or the lettering, I use another tag.
For the titles - our last ruling (though still a bit inconclusive IMO) seems to be in favour of title tags. Please note that it's better to use a franchise (or book series or universe) tag when the work is a part of one (though I'm unsure if we need to group all comics about a superhero like this and this needs a separate discussion).
That said, you have to be 100% sure to add the name of the author to a story-identification question. Unless you're asking for a specific story by a specific author, better just note in the question "I think it's a story by X".
