You can find "Notification Settings" under your name in the upper right menu.

The first batch of settings is about how things work:

• "Send me news and information" - Everyone should keep this checked so that we can email you.
• "Automatically follow conent" - This allows you to automatically follow things so you get alerts to things that you involve yourself in.
• "Method to use for content I follow Automatically" - Select how you wish to follow stuff. 
• Notification preferences - This allows you set how much alerting you get.
• On the right side is the Browser Notification which allows Gay Authors to alert you even if you aren't on the site.  They can be pretty intrusive.  If you wish to change them, it is at the browser level.

If you want to change your browser notification, here is a how to video:

The rest of the notification page allows you to set what you get as inline notifications or emails:

Hope this helps!
