New features in Ragic, along with updates for existing features, and some event announcements can be seen in the What's New? pop-up.
You can click on any of the announcements to read more details.
Click on any image thumbnail to see an enlarged version.
The pop-up will be hidden when there are no new announcements, but you can always display the announcements again by hovering on the Learn Ragic link on the upper-right corner of your account, and clicking on "What's New?"
