Here is s a thought if you cant give us access.
Why not poll us with a survey questionnaire asking us what sort of feature set club owners are looking for.
That way ;
we can input at least if we cant access .
You will understand if you are getting appropriate feedback for what this club feature should look like from your current testers , as it sounds like from last feedback its concentrating or a specific feature of club organization not all clubs would necessarily be interested in (although my club certainly are ) .
It would also help you understand how many would want to use that feature you mentioned as causing a lot of concern ( event organizing ) and understand the impact.across the board.
For sure it will also make sure how you would need to message roll out if you were to present us with a feature set that is not aligned with what the majority of club owners might want or expect . Messaging of the roll out in some respects is even more important than the product itself. If you don’t do your market research here with target audience it might not go so well . So whilst I might be super happy my appreciation might be drowned out by all those who didn’t get there wish list .
Finally if you really really must roll up to only another select few you will at least know who the most appropriate clubs are … because they would have told you in the survey
