Actually, now that I think of it, the later case is even more important. If someone wants to see all coauthored articles, they could look them up on the author override page anyway without the tag. But if someone is just reading a random article, there's no way for the reader to know that it's coauthored without the tag. So yeah, I think the tag is warranted.

Sharing credit should be easier. At least a co-authored tag would allow for that in a decentish way.

Since it doesn't tell you who collaborated, it would essentially tell you nothing.

It would tell you that the article is the work of two or more authors working together from the start, as opposed to a rewrite or a translation or a regular single-author article?

Also, to anqxyr, what about people who have no access to chat?

Basically, I'm just looking for a way to let people see how many articles are jointly-written works, and which articles those are.

If not, would it be feasible to implement a "co-authored" tag? I know Project Foundation was going to have a mechanism for equal crediting, but I'm more interested in having a record of the articles that were jointly-written.

I feel like all the digging we'd need to do is just go through author pages and double-check discussion pages (I'm genuinely curious, so I'm volunteering here to do some of that).

Thoughts?
