I have a client that has just been purchased by a larger company that uses Oxcyon's CentralPoint CMS. Currently they use Joomla to manage their site, but it will soon be moved to the CentralPoint system. Has anyone had any experience with this system? Any help would be great, the client wants me to help with the transition and make sure that they will not lose any functionality or aesthetics.

Some questions would be:

What language is it programmed in?
Can it be modified if their modules don't have the functionality that is needed?
How is Oxcyon's service?

Just hoping to find someone who has actually used this system to give some inside info so I know what I am in for...
