Starter edition provides Project pages. In every project page, there is a project issues section as shown in the demo site below:
The project issue section displays all issues related to that project. You can put your project page links in a menu item and allow users to browse the project they are interested in.
To be able allow public users to see issues and projects, you must remove access restrictions. The default is everything private.
In WordPress Dashboard,
1- Go to SimCom > Settings > Entities > Issues
2- Check on Remove access restrictions on frontend
This will make all issues accessible from public.
Repeat the same for the projects, picking Projects in the step #1.
Pro and Enterprise Editions allow you pick and choose which projects or issues can be public or private and offer more advanced listing options such data grids.
