I want to purchase a 50 user license for Share360 Standard, but I only want 10 users for Project. Is this possible?
Yes, you may purchase an add-on product with a different number of users than the main suite product, as long as the user number of the add-on is equal to or less than the number for the main suite.
When you purchase add-on products, such as Project or Web Forms, you ust register individual users to access those products. The admin should go to Admin Tools > Registration > License Select Users for Applications.
