Well, then tonight your gonna learn something new! It you look at the bottom of my post there should be a row of blue buttons on your right.
1.) It's says
quote and has a page and a quill little image on it. Clicking that will quote that individual post and take you to a new screen to post your reply.
2.) It should have a page and quotation marks. This is how you quote multiple posts. If you click it for every post that you want to quote it will change colors to show that you are quoting that post and then you simply click "Post Reply" and it will take you to the new screen with all of your quotations to post your reply.
3.) The last one just has the page and quill and if you click it will open up the quick reply box at the bottom of your screen
