 Can anyone edit Wikipedia? This is Lisa. Lisa is new at Wikipedia and wants to edit an article, but for some reason she can't. She realizes that the article is semi-protected. Why is that? Wikipedia is edited every day by thousands of volunteers from around the world. Truly, everyone can contribute their knowledge. It's a great system, and it's what made Wikipedia the largest encyclopedia and one of the most popular websites on the internet. In only a few years. But the World Wide Web is also home to many online trolls. Those are people who enjoy annoying and provoking others, and they often cause damage. To make Wikipedia's knowledge less vulnerable to such trolls so that they can't damage it or delete it altogether with just a few clicks, only auto-confirmed users can edit semi-protected articles. To get this status, Lisa has to make at least 10 edits to unprotected articles. Also, her account has to be more than four days old. Aside from that, more experienced Wikipedia's make sure that community-selected administrators find out about users who repeatedly break Wikipedia's rules and temporarily block them. Of course, they also check that the changes meet Wikipedia standards. For instance, they make sure that Lisa used a neutral tone and cited good sources. Even if Lisa makes a few mistakes at the beginning, it's no big deal. Great! When changes are undone, it's almost always for good reasons. Wikipedia is not about pushing individual opinions, but rather reaching a consensus together. Still, Lisa wants to defend her edit, so she uses the talk page to make a case that is objective, polite, and supported by good sources. Finally, four days later, Lisa has made her first ten successful edits. So her user account is now auto-confirmed. From now on, she can also edit semi-protected articles, move pages, or upload files.
