SMF is designed in such way that you don't get duplicate content, just refresh your index page and you will find noindex gone. Explain further, though you are on index page, but its not the actual index url and hence SMF is saying not to index it.

SMF has the noindex thing there because of the PHP session ID in the URL. We don't reject cookies in any way either. If you choose not to allow cookies, SMF will need the PHP session ID in order to keep track of who you are.
