Because of these misconceptions, edits by unregistered users are mistakenly reverted and their contributions to talk pages discounted. This practice is against the and of all projects. When dealing with unregistered contributors, the rule to remember is: IPs are human too.
You are an IP too. See here if you don't think so. The only difference between you and an IP contributor is that your IP address is hidden. When you , you hide your IP address behind a user name. Unregistered users are often called anonymous editors. In fact, because your IP address is hidden, it is you who is more anonymous. (Your IP address is still recorded by the software. It is simply .)
Remember this when dealing with unregistered users. They are not a lower category of users. They are not a special subset that we tolerate. They are not locust swarms intent on destroying your article. They are individuals, the same as you. Why does it matter that they have not registered for an account? Just as you deserve to be treated with civility and good faith, the edits of unregistered users deserve civility and good faith from you. As your contributions to talk pages deserve to be heard and counted when forming consensus, so too do the contributions of unregistered users.
Our readers are IPs too. Virtually none of our readers are registered users. When an unregistered user makes an edit to an article or posts a comment on a talk page, these are the views of one of our readers. That doesn't necessarily mean that their view should be given greater weight. It means that we should not discriminate against their view just because they don't have an account.
Many users misconceive that policy and guidelines only apply to registered users. Not so. Policy and guidelines affect all users, registered and unregistered, equally.
As a general rule, unregistered users can do everything that registered users can. Unregistered users may edit articles, participate in talk page discussions, contribute to policy proposals and do (almost) everything else that a registered user can do. There are, however, some specific restrictions on what unregistered editors can directly do without the assistance of an admin or a registered-and-autoconfirmed editor.
