How to use the membership plugin to restrict viewing access on Atlas Directory Theme..?

Hi,

I’m using the Atlas Directory Theme on my site (www.puertoricofashionindustry.com) which comes with a built in membership system that allows users to create listings on the front end of the site. I have also uploaded the WPMU Dev Membership Plugin and would like to use it in order to allow only registered members to view and create directory listings. I’d like for users to simply register for a membership on the front end and get instant access to the directory content and the ability to create listings. I’m wondering if someone has insight into how to achieve this. It’s my first time using this plugin. Thank you in advance.
