    Formal note: the answer you accepted is not the first one chronologically. If you mean "the first answer from the top" then please note each user can choose a sorting method independently. Therefore the term "first answer" is not well-defined, in general it can easily confuse users who see different order of answers. For future reference: if you really need to address an answer anywhere else than in comments under the very answer, link to it. In this case we know what answer you probably mean: the accepted one.
