Notifications
Notifications are the mechanism GeneWeaver uses to send messages within the application. There is also an option to receive email for notifications, which can be controlled from the Account Settings page.
Regardless of whether a user has been configured to receive emails, they will always receive messages through the Notifications page. The fact that you have pending notifications will be noted in the menu bar by a red indicator over the envelope icon.
The Notifications page itself is fairly straight forward listing the notifications that have not yet been seen in bold, and the rest of the notifications in normal font. There is a button at the bottom of the page that allows you to Load More Notifications so that you can get your full history of notifications.
