To answer your question: if you are on the default skin, you should see in any section; a red bar above the action bar (Where you can skip through pages). AT the far end of the red bar on the right is a purple bit where it says "Create thread". =)
Hope that helped, if you have any further questions please feel free to make a post in the TTF Support forum or ask any of the staff - myself (Site Owner), Jazzman Crothers or Onix Solo.
