Help to skill my communication

Hello Reddit, my name is Anass and I'm from Morocco, 34 years old. I have an idea for a marketplace site. I have been talking to some very smart people here on Reddit about my idea and they provided some valuable insights. However, I’m looking to sharpen my skills in communication. I’ve noticed while I’m emailing these very smart people that they have a certain level of comprehension of my idea, but they don’t fully get it—maybe because I failed to deliver a clear understanding of what I’m trying to make. So if anyone is interested in helping me develop communication skills on FaceTime or whatever you feel comfortable with, it would be a great help.
