I am not sure how to use the URL group feature mainly because there's a section concerning "regular expressions".
I have no idea how to use regular expressions even after visiting the link provided in the manual.
What I would like to do is protect access to certain custom post types to visitors. So I don't want them to be able to view nor create those custom post type posts.
Should I simply add: http://mydomain.com/custom-post-type in the page URL field or do I have to add a regular expression to that?
Thank you very much for your help,
