Hi Cem! Thanks a lot for your reply. Now I understand what you mean!

You mean the ability to publish content accross multiple Membership Levels (ALCs) - In your case, ACLs doctors + cardiologists + pediatric cardiologs, right? if so, then the 'Visibility' feature might be the best approach. (It's just a suggestion, though)

The same way in Studio, we use 'Visibility' for pages, blocks (e.g. visible to: Administrator, Moderator, Standard, Premium etc.), maybe we could use it on the content creation page to select the Visibility to specific membeship levels (ACLs) as well. Currently, you can set the visibility of a content (post, article, picture, video etc) to: Public, Friends, Relationships, Courses, Groups etc. only.

Why do I suggest the 'Visibility' feature? It's because achieving what you are suggesting, meaning placing the same members in multiple Membership Levels (ACLs), multiple Subscriptions at the same time (e.g. the same member is, at the same time, Moderator, Administrator, Standard, Premium or In your case, Cardiologist, Pediatric Cardiologist etc.) might be extremily difficult, I have never ever seen such a configuration before on the internet when it comes to subscription/membership-based websites whether they are free or paid. A member can only have ONE (1) active subscription at a time.

You CANNOT have a member in a plan called 'Cardiologist' and have him/her in another Plan called 'Pediatric Cardiologist' at the same time. Even Payment Gateways (Stripe, PayPal etc) will not be able to process two subscription/plan payments of the same user at the same time. One of the user's plan will be cancelled.

Things get very tricky because you are using Membership Levels (ACLs) as Categories to organize members and content on your system. That's add an extra layer of complexity to your website. Anyway, if such a setting works well for you and you are fine about it, then no problem. UNA is flexible enough and can actually be adapted to any use case.

Regarding Labels, this video by Andrey will help you to understand better the concept behind 'Hashtags, Labels, Channels' and how they work:

Also, you should consider upgrading your system as many new functionalities were introduced since UNA 12. And many bugs were fixed as well.

Thanks
