Shouldn't we improve the text in the textbox? Right now, it implies you earn ten points when it actually means need ten points in order to do that.
You need 10 reputation points to answer this question.
With my non-native eyes, I interpret "Earn ten points in order to answer this question" as "you need to earn ten points to be able to answer this question". This is emphasized by the word "requirement" afterwards. In any case, we moderators cannot change this text. Such changes should be proposed on the main Meta.
