[OJS 3.1.2] OJS 3 for peer review only- Is it possible to set it up so it doesn't show up on our journals list?

OJS 3.1.2.0

I have a journal that uses OJS for peer review only and the articles are published elsewhere. Is it possible to set it up so it doesn’t show up on our journals list (i.e., this page journals.uic.edu)?

Originally, I had the journal set up so it was not “Enabled to appear publicly on the site”, which meant it didn’t show up in our journal list. You could still access it via a direct link to the journal. However the problem with that solution is that it wouldn’t allow anyone to register. In fact, none of the links worked (for readers, for librarians, etc.). When I “enabled it to appear publicly on the site”, the registration link and other links worked but now it shows up in my list of publications, even though we don’t actually publish the contents of their journal.

Thanks!
