With YourSites you set up your own private website then install YourSites as a extension. This website will run Joomla, but its easy to setup and once its installed you won't even notice what web software its running on.
This site can can be on your local PC, on an online server or even on an intranet or behind a firewall. There is no need to share your client data, or details of their sites with a 3rd party online site management service. The data is under your control.
We love every single one of our users, without you YourSites simply couldn't happen! So we would love a review at the Joomla! JED so we can let others know about us too, please take a minute to write a review:

If you feel you have something negative to say, we would implore you to speak to us first, as we really really don't want anyone to be unhappy!
