I have been all over the Community. I've tried some links suggested to start a new post. Nothing. There is absolutely no icon/button to begin a new post.
There absolutely is. It's important to note that you have to be logged in to the forums and viewing the board you wish to post in to see the Enter New Message button.
There is no option to enter a new message from the main page, or any of the board grouping pages.
You should see the "Enter New Message" button at the top of the board where you want to post.
To post a new topic, go to the appropriate board (Home Phone, Fios Internet, etc,). Above the list of curent topics you will find a red "Enter New Message" button in the upper left corner. Click that button to start a new thread.
