Am I able to add Add-Ons after my site is completed?
If during the initial creation of your site you elected not to use any of the Add-ons, login to the Optuno control panel and make a request to your project manager. Each Optuno plan comes with a set number of Add-Ons included. Just select the Add-Ons you want and Optuno will install and integrate them for you within a few days.
If you've used up all of the Add-Ons available with your package, you can purchase additional Add-ons for $99 per Add-on (one-time fee).
