The Web Portal allows you to create web pages which your recipients can visit. Each web page will require a Menu Item to control if a recipient should be logged in to see the content.
To create a web page, you'll need a Web Template. This controls the general styling and layout possibilities and is designed in HTML. The template will define a series of Content Blocks which you can add, remove, and reorganise to control the layout of a specific web page.
Each Content Block can be set up as a Dynamic Block. This means that the content of the web page changes dependent on recipient data.
Have your developer help you make your Web Template. Additionally, developer documentation on how to make templates is available.
