We open this extensions directory (http://extensiones.nosadaptamos.com), with the extension Missing Metadata (Module for Joomla! that displays a list of menu items and categories, which have not been entered metadata (description and / or keywords)).
Our idea is to throwing useful extensions for Joomla!, mostly free and some commercial ones.
Our thanks to the contributors who took part in the launch of our first extension: Carles Serrats (without their invaluable assistance would not have been possible), Javier Gómez, Fernando Galindo and Maria José Valiente.
Extensions offered hope that you find them useful.
