Hello. My course went live some time last week. I worked on it for awhile, but I still do not understand this platform too well. If anyone can help me, I would  appreciate it:

1. Can you edit your course (adding more resource, etc.) after it goes live? If so, will it need to be resubmitted for review. If so, what happens to the students already taking the course?

2. If there a place where there videos at tips on how to use the tools in the Udemy platform?

Please help?
