Yes! Tags are the beating heart of Beamible. They provide some really interesting and valuable insights into the activities you're undertaking, but also how much you enjoy them.
In order to view all your tags and the percentage of time that they represent across your role(s), simply click on the 'Member profile' icon on the blue left-hand Navigation Bar.
This will take you to the 'Overview' where all this information is presented. You will also see the number of roles and activities you have, and the number of hours you work per week.
