Hey Eden,

You can actually install it on as many domains as you want as there are no restrictions to the installation. Having said that, support will only be provided for 1 domain only If you need technical support on multiple sites, I would strongly suggest you consider upgrading to the Unlimited version by paying the differences. You can upgrade to the Unlimited version by accessing it at http://stackideas.com/dashboard

Currently, we are having a Halloween day promo, 25% off all products and renewal, the total cost would be $105 for the upgrade from Community plan to Unlimited plan. You'll have unlimited technical support for your sites and Copyright Link-back Removal
