One licence costs 1 USD, which includes the use of one installed WMForum instance, and free updates for a year.

Only one instance of the software may be used on one domain. For a different domain (even if it resides on the same server), a new license is necessary.

The software may be used free of charge for noncommercial purposes. Conditions:

• There is no money, there is no forum. :)
• If you lack money, please write on mail, we shall think up something.

Enjoy.
