name or names?

The property proposal was for “names”, and initially MSGJ created it using this label as well, but then he changed it to “name”, making the current label “author last name”. Why? I think “names” makes more sense – people can have more than one last/family name. Lucas Werkmeister (talk) 17:10, 5 July 2021 (UTC)

Yes, by all means change the label back to "names" — Martin (MSGJ · talk) 17:17, 5 July 2021 (UTC)

Okay, that was fast :) changed English and Portuguese. Lucas Werkmeister (talk) 17:50, 5 July 2021 (UTC)

Use?

@Mike Peel: are you planning to use this property? — Martin (MSGJ · talk) 00:57, 4 April 2022 (UTC)

@MSGJ: Yes. This is the focus for an Outreachy project this summer, see phab:T300207. Thanks. Mike Peel (talk) 06:14, 4 April 2022 (UTC)

That is good to hear! — Martin (MSGJ · talk) 12:16, 4 April 2022 (UTC)

Sorry for the delay with making use of it - I was planning on writing code to do this myself, but never found the time, then realised it would make a good student project. Thanks. Mike Peel (talk) 12:51, 4 April 2022 (UTC)
