jCore server is the core system on which you can build your jCore client sites. This is the system that contains all the libraries and/or modules you would use for your client sites.This way if there is a new release or an important bug fix you won't have to update all your sites one by one for each of your clients, just update jCore server and all your client sites will be updated at once.
jCore is an open source content management system. It is written in PHP and distributed for free using the GNU General Public License. What really sets this CMS apart from most of the others is that it is designed specifically to help manage multiple websites from one place. If you are running a service where you create and manage websites for clients, this is really an exceptional option for you. To accomplish this the developers broke it up into two sections, the jCore server and the jCore client. You just need one server and then a client for each site. It may sound complex at first, but it really is quite easy.
The developers have done a good job at keeping it updated with the latest features so that the sites can be quite advanced. They have also done a good job at keeping the back end fairly easy to use so you don’t need to have a lot of experience running websites. It is recommended that you have at least an entry level understanding of PHP if you want to do anything more advanced, but it is not strictly necessary.
