We host and maintain the site because it is a complete series of WordPress MU, settings and plugins, and our clients find it much easier to have us handle that. So you can get back to the job of creating.
But while we host the WordPress site for you, we are NOT selling or reselling hosting packages so there is no ftp access or hosting control panel.
While we do not give ftp access, because of security reasons, we are open to adding any plugins or ideas you might have. You can make feature suggestions and if the plugin will work and is coded well enough we will definitely consider adding it.
For advanced customization, we have a built in custom CSS panel where you can customize you site beyond the tons of options we have given. If you need more than that, we can create a custom theme for you and even work with your designer on the programming of it all. More about our customization packages.
