anruan23, cookiebaker is correct that we do not post identifying information here, and you will have to have been posting and conversing with people here for a while to get access to the private messaging.
I suggest that you start out by explaining in your posts what information exactly you want to hear, what questions you intend to ask, and how this information will be used. I would like to know these things myself.
Why is the video call needed? Can you get the answers you want from people here in the forum instead?
It is pretty risky for people to give someone they don't know their phone number in a forum even if it is a private message, and then allow recording of a zoom call without knowing how that video will be used. But that will be up to the people here if they want to.
Don't know if you will have time to get private messaging access by next week, which is why I am asking you if getting your questions answered here wouldn't work instead. I suspect that if you post a list of your questions, you will get a lot of people willing to answer here in the forum. I would, as long as they were not personal questions.
