Generally while signing up for popular services like Twitter and YouTube, you may have allowed the default email notifications or selected some options and never went back to change them. Over a period of time, these could be annoying as you might end up receiving hundreds or emails every day.
Notification Control is a simple website which displays the direct links to the notification control or settings page for most of the popular social networking site. Although you can easily get the notification page individually from each site, this site makes it faster.
The service provides links to Twitter, Facebook, Tumblr, YouTube and other popular sites. If you are logged into these sites, clicking on the link takes you to the notification page of respective sites.
This site does not have any extra features, but its very useful to quickly access the settings page for social sites.
