Hello, I'm new to the platform! I hope that some questions will be answered} Is it allowed to have multiple accounts on the platform? Can I assist you in providing the courses? Is it allowed for one of my friends to participate in the same session? Am I allowed to submit one of the Friends courses with his permission? Am I allowed to ask an expert to make a professional video tutorial for me and my account only? Is it permissible for me to participate in presenting the courses with a friend or professional friends?
