For those of you who would like to enable email notifications, but aren't quite sure how, here it is in 3 easy steps!
FIRST: you need to be saving your favorite addons to your favorites list!
On each addon's download page, there is an "Add Favorite" button right below the big "Download" button.
SECOND: visit your favorites list on the site.
This is where you can see if any of your favorite addons have been updated. Not sure how to get here? Hover your mouse over your username in the top-right of any page on the site. This will open a dropdown menu with "My Favorites" as the second entry.
THIRD: change your email setting in Preferences.
The "Preferences" link is in the left-hand column of your Favorites page. On the Preferences page, the very first setting is for your email notifications. Be sure to click the "Update Preferences" button at the bottom to save!
