RegUser operation allows to create a new account for a user in the MediaWiki Server by passing specific information such as the name, password, domain and email. In the same way as form Login action, sensitive parameters must be passed by POST form.

Sample request and result:

Request

                                          rucaptchaword are not included in the request, the result will be “MissingCaptcha”.

   username: Raquel                     Normalized runame, also returned as a cookie
   userid: 12345		        Also returned as a cookie

Internally, there are two options to create a new user account:

• A logged in user creates a new account. In that case, after performing the action regUser, MediaWiki Server keeps logged in the user with the initial login.
• An anonymous user creates a new account. After performing the operation successfully, the anonymous user will be then logged with the new login name. That is the reason why a token and user id is returned after this operation
