 | This page in a nutshell: Everyone – including you – can make improvements to Wikipedia, the free encyclopedia. |
You do. Yes, anyone can be bold and edit an existing article or create a new one, and volunteers do not need to have any formal training. The people who create and edit articles on Wikipedia come from many countries, with individuals who all bring something different with them, but most importantly a willingness to help in building a free encyclopedia of reliable information. Any contributor to this encyclopedia, unregistered and registered alike, is called a "Wikipedian", or, more formally, an "editor" of the encyclopedia. Almost all Wikipedians are volunteers. Other categories of Wikipedians have emerged as well.
