Is there a knowledge base(of questions) for membership? or any spefic plugin.

I'd like to search for and read through other members questions and a knowledge base related to a specific plugin before I ask a question.

I'm find it really hard to navigate the discussions other than through a search which seems less than optimal.

I found this thread but even when trying to use tags or the links in the threaded question no way to limit my search to just membership plugin.

https://premium.wpmudev.org/forums/tags/membership takes me to an empty page.
