Messages that support GENDER in MediaWiki

I thought GENDER is supported by default, but according to GerardM post it isn't?

So yeah, first, it needs to be enabled, second I need a list to start working. Thanks.

Gender is enabled, but only for the "current user". If you want to use GENDER for a referenced user, this is not possible without using a parameter. GerardM may not have been clear on that. For more, see Gender.

Yeah, I know about this problem, but it isn't restricted to Arabic only. If a messages doesn't support GENDER, it doesn't support it for all languages (in this case, if necessarily, I'll need to add a note here in Support page).

Let's stick to actual use cases. Please report whenever you think GENDER should work in a particular use case but does not. Please describe it a clearly as possible. Thanks.

OK, I will. So, here, I need a list of all messages that support GENDER so I can start. It won't help me and the Arabic translation only, but all teams that want to use GENDER. Is that possible?

See documentation.

Great, this was helpful. I noticed that only very few messages support GENDER (according to the docs). In Arabic, any message that contains "user"/"contributor", for example, needs to have GENDER support where possible. Should I report any message here?

Use the gender in your message, and test if it works or not. If it works, document it. If it doesn't work, report it. Thanks.
