Hello @livinglifesmiling! Now that The Exchange has moved to a new platform the steps are a little different.
Go to the main menu at the top of The Exchange, click Practice Management and scroll to the bottom of the drop-down list for Product Ideas.
After you select Product Ideas you can click Suggest an Idea, at that time you can enter a subject line and the description in the Body field. You will also want to choose your product under Choose a label on the right side of the screen.
