Change wording of post new thread and reply buttons in message boards portlet

The wording of the "Post New Thread" and "Reply" buttons is confusing on the page where you enter the message text in the message boards portlet. It is confusing that you have to click two buttons with the same text in order to post a thread or reply (e.g. "Post New Thread" to go to the page to enter the message text then "Post New Thread" to submit the new thread). It would be preferable if the button on the page to enter the message text was simply labelled "Post Message" or something like that. Having both buttons with the same text implies that they will both perform the same action where as one is to go to the page to enter the message text and the other is to submit the message.
