A new version of the notifications add-on is now available to download and is highly recommended for anyone using 1.3.1 as it resolves an installation issue preventing it from working on certain setups. Also by request, I have added in a preview functionality in the admin area when you are editing your Notifications settings. Once you save your settings, you can click on the “Preview” button to generate a dummy notice. This will be handy for testing custom CSS stylings without having to generate points to trigger a message.
You can download your copy from your accounts Downloads section or if you have setup your license, an update notification should appear on your Plugins page.
