This question already has an answer here:
Someone asked a question tagged php, cookie and setcookie. I answered the question. The answer was accepted and up-voted by the asker. Now my php score (in my profile) has increased by one, but my score in the other two tags did not change.
How does scoring of tags work? Do answers count only for the first tag used on a question?
(Note: the other tag scores increased less than two hours after this question was asked.)
