is it 2 cents or 3 cents per post?

It actually varies. I did an experiment once where one day I provided only one response and the next day I provided on one discussion. Both times I received 2 cents. On the third day I did lots of posts and lots of discussions and it averaged out to a little more than 1 cent per post. So it does vary.

I heard it was only 1 cent per post, so I'm thrilled to hear it's double or triple as much as I thought. I can't tell you, but quality, posting own topics and solving topics earn you extra points as well :)

i dont know abt one response ,but i m say that for 100 post it gives u about 2 $ ..... it also depends upon quality post and also for best response....

I dont know man.. no one know..

I think it's more about the quality of response than the quantity. I saw mention of a proprietary formula. I think that gives them the discretion to treat it the way they choose to.
