Licensing System & Admin Users

We often get asked how licensing works with respect to users. So, here is the explanation of PHPKB's licensing system.
The licensing system of PHPKB knowledge base software is based on the number of admin users that can be created to login and add/update content in your knowledge base. Admin users include Writers (Authors), Editors, Translators and Superusers. There is no limit on the number of end-users that can access the public area of your knowledge base. So, you can have unlimited end users (readers) who can browse your knowledge base or login to the public area.

An admin user account is a user that would be able to login to the admin area, create/manage articles, and be an author or admin. You can have unlimited "public" users (readers) with all license options.

Yes, you can always choose to add more admin users in the future to your existing license. You need not to pay full amount for upgrade. All you need to pay is the difference between the cost of upgrade license and your already purchased license. For example, If you have purchased 5 admin user license of PHPKB knowledge base software and you'd like to upgrade your license for 15 admin users, then you need to pay the upgrade cost for 10 admin users only.

There is no limit on the number of users that can view the knowledge base. If you do not plan to restrict access to your knowledge base, people would not need any special accounts to view your knowledge base. This means you can have unlimited number of users that can access the public area of your knowledge base. They can do this in the same way as they view your website.
