Can you give me an overview of the reply features. Examples are quick reply, quotes, multi qoute, post reply I believe there is 1 or 2 more choices on responding to a thread or comment. How do I choose which feature is more appropriate to use? How do I use it correctly? How do I direct my reply to the main top thread verses someone else's comment?

Post reply for main thread, quote for reply to a specific post.

What is the difference between quick reply and post reply, it doesn't seem any quicker? Does it have any another advantages? How do you use multi quote?

yeah i wouldnt mind knowing that, when u figure it out let me know.

Quick reply allows you to reply in the box at the bottom of the page, I use it all the time, post reply opens in new page.
