If the site you're visting doesn't allow registration, or you think you might prefer another one, you can find a [list of public servers here](http://dir.friendica.com/siteinfo), and find one that meets your needs.
The first field on the Registration page is for an OpenID address.
If you do not have an OpenID address or do not wish to use OpenID, leave this field blank.
If you have an OpenID account elsewhere and wish to use it, enter the address into this field and click 'Register'.
Friendica will attempt to extract as much information as possible from your OpenID provider and return to this page with those items already filled in.
You may also occasionally receive notifications of incoming messages or items requiring your attention, but you have the possibility to completely disable these from your Settings page once you have logged in.
A nickname is used to generate web addresses for many of your personal pages, and is also treated like an email address when establishing communications with others.
Due to the way that the nickname is used, it has some limitations.
It must contain only US-ASCII text characters and numbers, and must also start with a text character.
It also must be unique on this system.
This is used in many places to identify your account, and once set - cannot be changed.
If you use your account to manage multiple '[Pages](help/Pages)' and these all have the same email address, please enter the nickname for the account you wish to manage.
A ['Tips for New Members'](newmember) link will show up on your network and home pages for two weeks to provide some important Getting Started information.
