Go to your Campaign Search page: <a href="https://app.roll20.net/campaigns/search" rel="nofollow">https://app.roll20.net/campaigns/search</a> Below the name of the campaign is 'Edit Tag'. Click on that and add a tag. Click 'Im Done!' Near the top is a search bar to input a tag name. This allows you to find a campaign in all of your various campaigns (assuming you have many). - Gauss
