I was excited to see that the beta had been released today, although not posted to this thread. Was that because the features discussed here are not yet fully implemented? Trying it out I was able to add multiple author-boxes to the main post, but was not able to successfully create a “guest author” who is not a fully registered account holder. (There is an interface to do so, but in my experience it wasn’t working.)
In addition I had these other issues with the beta plugin:
1. I had setup my theme to show Simple Author Box at the top of the author archive pages for each author. However, now the “guest authors”* from one post now have their author boxes show up on that page as well. (*These aren’t actually “guest authors” but just co-authors who are other registered users on the site, each of whom should have their own archive page, and shouldn’t be listed here just because they co-authored one post together.)
2. It should be possible to attribute a post to a “guest author” without listing the name of the person who posted the article. For instance if User X posts a piece by guest author Y, now it seems to show Simple Author Box for both X and Y. However, it should be possible to only show Y (unless it is co-authored).
3. There is a distinction between co-authored pieces and guest authored pieces. Right now the plugin doesn’t seem to be able to distinguish. If two registered users X and Y write a piece, Y shouldn’t be listed as “guest author,” but then there is also the possibility of the situation listed above in issue #2.
Apologies again if these features were not ready for testing, but I am eager to get this implemented so I wanted to take a look.
