Gender support for instances of username (gsw)
Individual messages which need gender support and don't have the GENDER keyword should be reported: maybe GENDER works already (and that's useful to note in /qqq), but it needs to be properly conveyed to translators.
As for neuter, we had a request for neuter from another German language, please add your use case/information there.
Many thanks for pointing me to the right places.
With regard to reporting: There are some messages like MediaWiki:Notification-edit-talk-page-email-batch-body2 where GENDER is already being used, but there is no mention of it in /qqq. If I understand you correctly, there is no need for reporting such a message on the Wikimedia Phabricator and I can just edit the /qqq by myself. Is that correct?
