How do i submit articles in wikipedia ?

to submit a whole new one you must search it and it comes up with no results and it will offer for you to make one. you must be a member. it is free though. at the very bottom of the pafe there is an edit button click that than you can change things. some pages are locked though and cannot be changed. they screen everything you change though manualy before it appears. hope this helps!

Umm, you do not submit articles in Wikipedia, you just edit them like almost like any HTML document.

Although when people see it, they will decide to keep it or not.

First, you have to search for the term that you wish to create an article for. You should arrive at a results page, and, at the very top of the page, in small red letters, it should read "You searched for [topic]", [topic] being what you searched for. Click on [topic], and it should lead you to a page so that you can create an article with that title.

Write your article, and, when you're done, click "save page". :)

You have to be registered and wait a few days before you can create an article. In the meantime, you are able to edit all of the articles that aren't semi-protected or protected.

However, don't start an article unless your subject meets the standards of the notability policy. You're just wasting your time, as Wikipedia will delete it as a violation of policy.
