How do I use the different "Reply" buttons?

The Quote Reply button at the foot of every post brings up a reply form pre-filled with that post's full text. Use Quote Reply with care. Habitually quoting the entire previous post only clutters a topic with needless repetition. The better choice is often Add Reply or Fast Reply.

The Add Reply button appears in the header and footer of each open topic. Clicking it brings up an standard reply form with format controls, smilies and preview.

The Fast Reply button in the footer of every page toggles a simple reply form. To set the Fast Reply form to open automatically at the end of every thread, click My Controls, Options / Board Settings, Posting Settings.

The MultiQuote toggle button selects multiple posts to be quoted when Add Reply is clicked.
