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. takes me to an empty page.
