Thanks for your opinion but I still would like to apply to become an admin. I want a rollback button to help me remove vandalism and to be able to warn people that vandalise and if they keep doing it ban them. 

 I would also like to suggest a ban from editing pages for people that after a warning continue to vandalise, If there is not already one. 

 By the way the image at the top of the page of http://wikipedia.org does not show up
