From what I am aware, one gets points for helpful and correct answers.
you will get a point per thread apart from correct and helpful answers
And where did you read that?
I don't recall seeing anything that said there would points for merely posting a response. If they do that they might as well trash the entire points system, because threads will be flooded with 'me to' responses from people trying to drive up their point count. A problem that we already see too much of, but would be much worse as people wouldn't even have to consider whether their "answers" are correct or even if they have any bearing at all on the question.
