Couldn't do without it

Turned out to be an essential plugin for my site and has worked great, especially with the Guest Author option. (My site’s an academic one, where people have, say, co-authored papers but don’t care to register with the site itself.)

Only the smallest caveat: anecdotally and via the Plugin Performance Profiler, Co-Authors Plus apparently uses the most memory of my plugins. So the same advice we all get when we have too many plugins and a fair amount of content…consider caching.
