Editing Help:Preferences (section)

== Watchlist ==
:{{myprefs|Watchlist|Details|[[mw:Help:Preferences#Watchlist]]}}
The watchlist options include which pages, and what "recent" means to you. If your {{myprefs}} has "'''Email me when a page or file on my watchlist is changed'''" set (at the bottom of the "User profile" tab), then only by visiting a page will you actually set its email notification flag.
<section begin="email" />Once you miss the email for a particular page change or don't visit the page (or ignore the email), ''you will not receive any more emails for that page''. You can still dutifully monitor that page by its watchlist edit-summaries, but its particular email notification flag will remain unset until you visit it. This facilitates monitoring a large watchlist while preventing potentially useless emails to you.

In case you want to set ''all'' email notifications anyway, you can at any time mark all pages "visited". If your {{myprefs|Gadgets}} has "'''Display pages on your watchlist that have changed since your last visit in bold'''", then your watchlist will have a button labeled "Mark all pages visited". That button will effectively set all of your email notification flags.<section end="email" />
