Jeez, just answer the question guys. :rolleyes2
del bra said:
whats the difference between the reply button on the bottom right corner of a post, the one at the bottom of a page, and the add reply on the left?
The reply button on the bottom right corner of a post is just a shortcut to the box at the bottom of the screen. Alternatively, you can click "quote" beside it, and you'll get into the advanced reply screen with that post already quoted for you.
The one at the bottom of a page is the quick reply box.
The add reply on the left is actually a reputation tool, as someone described. There are a few threads about it around. If you can't find them using the search, just ask.
