Hello SK Furkan,
As you are a new member, you must know some rules pertaining to this site. The present site is not as that of its sister sites, allowing everyone of its persons to participate in every aspect. For to participate in those sections, you must get the permission from the webmaster who gives you that allowance by seeing your ability through the forum sections.
I am not clear about the section which you have mentioned as there are some sections which are to be opened by the webmasters. They will do it when they require and they would ask through a forum in the main page itself.
I think you have got the necessary information, if not please give the respective details which you want.
