What is the best user role to assign to new registrations using your Q&A plugin


I am just getting started installing Q&A to setup a simple Question and Answer site.

I would like to know what your recommendation is for assigning a role to a new registration.

I see there is a a new role in my system “QA Visitor”. Should I use this as the default role or use “Subscriber”. What are your recommendations and your recommended default settings for this role?

Thank you,
