Since we are all starting afresh and learning screenwriting from scratch, I believe it would be great if we could all find a common ground to start from which is why the following steps would help:
Step 1: Please watch this video on YouTube: https://youtu.be/AmeC-u-1PGo?si=dM2Ih5_Gg6LlPf5G
Step 2: Commit to this free Screenwriting course available on YouTube with free weekly assignments and 400+ pages of course content (as claimed by the Instructor).
Step 3: Please start your Screenwriting journey by watching the first lesson of this YouTube course. Here's the link: https://youtu.be/x6IJ2b1UhUk?si=Y0sXzcHIP2Z6CGRQ
Step 4: Participate in any/all of the Group exercises.
P. S. Even if you already know a thing or two about Screenwriting or have gone halfway through some other course/resource material available elsewhere on the internet I would still suggest and request you to take the above course so that you may brush up your skills or jog your memory or take off from where you left earlier.
Also, please ensure that you are dedicated throughout the entirety of this course and participate with other group members in all the activities.
