Registering as a user
To add or edit content on a Drupal site, usually you have to first be registered as a user. (Sometimes the site administrator has chosen to enable "anonymous" posts of things like comments, in which case you can post them without registering.)
In some cases, a site administrator will add you as a user. If so, they will send you a user name and password that you can use to log on.
Otherwise, look for a small form called “User login” on the main page of the site you want to register with (usually on the right or the left of the page). Click the link that says "Create new account".
