The cost is. 70 dollars a month US. It cannot be hosted on any other server only on Hoopla's. All upgrades are free and the price is a fixed figure due to our long relationship with the company.

Phpbb I set up just in case no one wants this present version then Phpbb is already running on the GNI hosting server.
Hope I am not confusing anyone
