If you want to use TagCrowd in a business setting, i.e. in the course of doing something you are paid to do, or making something you plan to sell, you can buy a $19 USD license for commercial use of TagCrowd by up to 5 users, without restriction, including all future versions of TagCrowd.
That means unlimited clouds for you and your company, forever and ever.
Buy however many licenses you need for the size of your organization.
With a license you can freely put clouds on your commercial website, your powerpoint presentation, office wall, in your book, annual report, on your t-shirt, or wherever. These license fees support the server costs and continued development of TagCrowd.
