* '''మీ ఈమెయిలు''': You may optionally register your e-mail address (it will not be shown publicly on the site). This will enable you to reset your password by clicking the "Mail me a new password" box on the [[Help:Logging in|log in]] screen, if you forget it. Additionally, it will enable other registered users to send e-mail to you from the "E-mail this user" link on your user page unless you've checked the ''disable'' box (see below).
*'''Disable e-mail from other users''': If you check this, users will not be able to send you e-mail by way of the "E-mail this user" feature.
Although your username is not necessarily your real name and could therefore be called a nickname, the term "nickname" is used here for a name you may optionally specify, different from your username, for when you [[Help:Automatic conversion of wikitext|enter your signature]] with <nowiki>~~~</nowiki> or <nowiki>~~~~</nowiki>.
(If you use the edit toolbar for signing, remember that it gives two dashes before the four tildes.)
==== Raw signatures ====
However, there is even more versatility. You can use any text as your nickname.
From [[m:MediaWiki 1.5|MediaWiki 1.5]] the behaviour of signatures has changed. In older versions of MediaWiki, wiki and HTML markup could be entered in signatures, even without "Raw signatures" being checked. So entering "<nowiki>]] | [[User talk:Name|Talk</nowiki>" as your signature would have also included a link to your talk page in your signature, producing an effect similar to: "[[User:Name|Name]] | [[User talk:Name|Talk]]". This is now no longer the case.
