Clan Limitations & User Area & User Registration

So I have a few issues here.
Firstly I want to disable the create clan option and how do i put it somewhere else in the navigation ? If its out of your support scope then at least tell me where can I get the php file which has the create clan code.
If its not possible then how can i restrict a user to create only one clan. I dont want him to keep on creating clans. How do I restrict him ?

Secondly is it possible to redirect user to his profile page after login ? I want the users to be more active in their profile rather then the home page.

Another thing is I want the email activation thing so If I add any plugin for it will it work ? or Atleast how do I add captcha in the registration from ?

Lot of questions here but then you could get an idea about the expectations from this theme 🙂 I like the theme just if you could help me out here it will be really great
