This component allows you to administer totally separate multiple joomla installations from one joomla site. Any users added to your joomla site will be automatically added to all your other sites. Any changes made to users or deletion of users on your site will be reflected across all your other sites. Please note that this component was developed quickly to take care of my problem of administering 10+ joomla installations. If you are in a similar situation, this component is perfect for you. This component has only been tested locally and on my server, so use at your own risk. I would love to get feedback and/or testing from other people. Be sure to take a look at the README. 

With Joomla, building and managing dozens of websites all day long is gravy.__* The problem is not how long it takes to setup your websites, instead its trying to keep up with the settings, configurations, passwords and other administrative settings__*. This joomla Jtex_multi_web_manager extension is not a substitute for managing your websites from a single point,__* nevertheless its a useful extension when it comes to getting multiple websites admin settings (joomla or not) at one single frequent destination:__* your joomla back-office. With this extension, passwords, emails, configurations, meta descriptions etc..are at your fingers or click at any given time. 

This project boosts two multisites components developed in parallel. Both components makes it possible to run multiple sites using the same Joomla 1.0.x installation.

The "Original Version" patches a few Joomla source files and aims to provide multisite capabilities within subdirectories of your existing site. Distinguishes content and entities between sites by assigning them different database prefixes, easily administrated through the backend.

The "Alternative Version" enhances OpenSEF's (recently renamed to NuSEF) multisite feature and utilizes a non-patch-approach similar to the one of Joommsites (a now abandoned multisite project). Provides easy configuration of subsites residing on different domains than the original site (as well as in subdirectories). Uses one database prefix for all subsites and distinguishes content by invisible low-level database filters, allowing content-per-content filtering in addition to subsite-per-subsite filtering.
