Hi. Welcome to Wikipedia, but it is not a site like Myspace for people to write about themselves and their friends. It is a project to build an encyclopedia, and you can find out more about it at the WP:Five pillars, the WP:Welcome page, and the guide to writing WP:Your first article. Also, I thing it would be a good idea for you to read Wikipedia:Guidance for younger editors, particularly the section headed "Your safety and security".
