My use case:
I have several internal service desk projects that I would like to allow employees to be able to submit requests and create accounts.
I would like to set up a public service desk project that I would like our customers to be able to submit requests and create accounts.
Currently, if I go to the URL of the project that I'd like to customers to use, if they click on the top level 'Help Center' link, they can see all the internal service desk projects.
How can I limit access for my customers so that they do not see our internal projects?
