GENDER
I see the content of the qqq-subpages (that documentation?), but I don't find your quote from docs of any of the 5 updated gender related messages. This note confuses too, if I translate it into language where there is no appropriate grammatical gender to use.
Ah, you're right, the docs were eliminated by a local edit. I've restored them now.[1] Thanks for noticing it, I hadn't thought of a conflict. :)
That has to be taken with a grain of salt; grammatical gender can also include lexical gender, which even your language most likely has from what I recall.
Lexical gender as much as I understand is the case for English he/she and that can be taken with a grain of salt. Indeed, there are some rare examples in Estonian too, e.g. equivalents of king and queen are separate words in Estonian (so that the male word isn't used for female person). But I don't choose my gender for MW interface to be addressed or mentioned as a king or queen, isn't it? Or even if I do, that isn't easy to figure out contrary to he/she and other more obvious examples above and that's where the confusion comes from.
