Related to my previous suggestion: [We should have a way to know if someone is a native speaker.](https://japanese.meta.stackexchange.com/questions/156/we-should-have-a-way-to-know-if-someone-is-a-native-speaker)

I was wondering is it ok if we have an option to indicate something along the lines of "please only reply if you are a native speaker" in a 100% less rude way and as such only native speakers will be able to give answers (though perhaps others could contribute in comments too).

Well of course if we explicitly tag "Please reply only if you are a native speaker" to our questions that would seem just too rude.

So i was thinking perhaps a checkbox for us to *indicate* our desire to have people reply only if they are native speakers, but of course even if they are not, they are 100% free to answer the question (it's an optional thing, just to politely indicate our desire you see)
