Are you confident that this works as expected? I.e. if an article had 20 authors, and a lazy editor had only written the first two, will the template still display the "et al"?

(Presumably that is what the etal value does, but that didn't used to exist back in the day...)

[GlazerMann]

@ms609 the display=etal is fairly new. This only fixes cases where editors list the last author at etal.

Great, well let's give it a go, but do keep a careful eye that the output renders as expected on WP!
