help when 'Plural' syntax is not accepted
You're lucky in that someone is even willing to listen to you. I've been trying to correct the Portuguese plural for years to no avail, despite the fact that even CLDR agrees with me. The first thing that they usually throw back at you is that you need to convince CLDR. Once you point out that CLDR is already correct and convinced, and agrees with you, and MediaWiki is wrong, they'll push onto you the job of correcting it yourself.
