In the Web Portal menu there is now a Power-up option in the top right of the menu.
When you select Power-up, you will see a list of available add-ons available to see to your Formitize experience. You can also see what you already have set up and what you don't. If the Power symbol is green then it means that you've already opted in for a particular feature.
To opt in for a feature, you can then select the feature that you'd like, and in the next window, select the Upgrade Now option.
