Hi, JonathanBZuniga, and welcome to the Community,
Now I understand!!
There is no new post green button on the Community's home page or main dashboard. You have to click on one of the message boards, like my screen shot shows in my previous post where I had clicked on the Android message board, and then snapped my screen shot, and on every message board at the upper left corner is where the "start a new topic" green link or button appears.
Thank you so much for uploading a screen shot!
