Mambots have been renamed as Plugins.

Mambots were introduced in Mambo and offered possibilities to add plug-in logic to your site mainly for the purpose of manipulating content. In Joomla! 1.5, Plugins will now have much broader capabilities than Mambots. Plugins are able to extend functionality at the framework layer as well.

The Joomla! Core Team consists of volunteer developers, designers, administrators and managers who, together with a large range of Work Groups of dedicated community members have taken Joomla! to new heights in its relatively short life. This well-oiled machine is often copied but never surpassed. Joomla! has some wonderfully talented people taking Open Source concepts to the forefront of industry standards. Joomla! 1.5 is a major leap forward and represents the most exciting Joomla! release in the history of the project.

The FTP Layer allows file operations (such as installing Extensions or updating the main configuration file) without having to make all the folders and files writable. This has been an issue on Linux and other Unix based platforms in respect of file permissions. This makes the site admin's life a lot easier and increases security of the site.

You can check the write status of relevent folders by going to ''Help->System Info" and then in the sub-menu to "Directory Permissions". With the FTP Layer enabled even if all directories are red, Joomla! will operate smoothly.

NOTE: the FTP layer is not required on a Windows host/server.
