Stack Exchange Notifier is an extension for Google Chrome. It is a handy extension for Chrome that displays your current reputation, badges on Stack Exchange sites and notifies you of reputation changes. Also, you will get notified of comments on your own posts (questions and answers) that are not older than 1 year and of any comments that refer to you by @username in a comment, even if you do not own the post (aka mentions).
All StackExchange sites are supported.
