I frequent several other forums which like this one use this forum software. But I cannot figure out what the purpose is of the "Quote" button that sits adjacent to the "Reply" button. If you click it, it turns read with a "-" sign, which I have always assumed meant that the quote feature was turned off. However, it doesn't appear to affect the quote feature since whether it is in normal mode or the other mode after being clicked and then clicking "Reply" the original post is quoted in full.
So, can someone please explain what this "Quote" button is for?
