It would be great if you mentioned on the 'Help pages' (which might help people) that it's not possible to start new topics when you are newbie.

I was reading this page
https://bitcointalk.org/index.php?action=help;page=post#newtopic
(the page which might have helped me to start a new topic) for 15 minutes and no clue about why I was not able to start a new topic.
