How to Manage and Modify Default Community Page Content in Dryfta

Can I add new content about publications? If not, how can I manage or replace its content?

To add new content such as a page about publications, use the Website Designer tool in the admin backend. 

Navigate to Modules > Website & Apps > Website Designer and click on the Content Pages tab and create new pages with your desired content. 

This way, you can customize your event website by building additional pages without needing to remove default ones.
