Not influencers.
Actual researchers.
Inside Sunday Club you’re with people who have tested, documented and studied the same materials you’re researching - not someone selling a course.

Why this community exists
Most of what circulates in this space traces back to a reseller, an affiliate link, or someone who read the same post you did.
Verify the documentation. Then verify the source.
Sunday Club members test, document and study these materials directly. When someone answers your question, you can ask them how they know.
Trace the claim. Then trust it.
What membership includes
Documentation, and the people behind it.
Credible information is two things: records you can check, and practitioners you can question. Membership gives you both.
Documentation Library
Product profiles, analytical documentation, research summaries and an education feed - kept current and organised so records are easy to locate and compare.
The Researchers
A peer community of people working with these materials directly. They share findings and assemble their own study breakdowns - not repackaged content.
The Insider Channel
A members-only channel that exists nowhere else. Announcements and limited releases are posted for members here before they appear anywhere public.
Organised for verification.
Sections are built so a document can be located, re-read and compared against another months later - the way records are supposed to work.

Then trace how they know.
Anyone can restate a claim. Sunday Club is built so you can trace one - to the documentation, and to the member who put it there.
