This is a wonderful community but nothing in this world is perfect

I have no prior experience or knowledge for computer science, online marketing, web design and writings, so it is very challenging for me to learn in WA. But I am trying to find a way to learn somehow.

I have been trying to learn SEO including local ones. So I made a plan to learn it from six of Jay's webinars and I started from watching "SEO 101 The Basic". I sent PM for my seven questions to him yesterday. This is not written instructions so I was unable to understand what he said exactly, is or isn't and 15 or 50. Also, he was using Yoast instead of AIO SEO, so the interface was different. These things caused me to ask extra questions. He replied me and answered my questions promptly. But I did not understand all of his answers and wanted to confirm my understandings, so I send my second PM to him.

Then, I got a reply from him.

"I feel that all these questions have been covered and will now consider
the thread closed. I need to limit the time allotted for questions
otherwise I will not be able to help other or grow my own business."

I was respected him as a super expert until I receive this reply, but now I am disappointed with him. I wanted to tell him that why don't you resign from an ambassador's position? But I replied him instead.

"Sorry to ask so many questions but many of WA members are far from an
expert like you plus English is their second language including myself.
I wasn't sure what you said in the video, 15 or 50 and is or isn't.
Now I feel that I am getting to learn why some people complain about
community. Anyway, thank you for answering my questions twice."

Am I asking too many questions? Should I stop asking subsequent question(s) after I receive a reply even though I still don't understand? About three months ago, I inquired that if I could get help by phone in order to avoid subcequent contact but WA did not use phone assistance.

Thank you,

Tomoko
