Welcome to NT!
I see you've posted in the MS forum. There may be a delay before your posts actually appear, but you're doing fine.
Are you wanting to start a new thread? If so, exit out of this dialogue and you should see a 'New Thread' option at the upper left side of the screen. It looks like the posts you have made are tagged at the end of someone else's 'thread'. So, just exit out of the thread and look up yonder left and you'll be able to start one of your own.

Hope this helps!
