ok I figured out sophiemom's answer....

different "skins" have different buttons. regardless of what a persons buttons look like (tried it in all skins lol) the first button under the signatures of the posts you want to reply to is the one that will tell you if you are on someones ignore list before you waste time writing posts....

Sophies mom.... if you look at your buttons in the screenshot you posted your first button labeled quote is the same as my reply button. use your Quote button instead of the quick reply box.

it is always the first button at the bottom of the post you are reading regardless of what style (skin you have your display settings set at)
