Magento Question:

Magento supports installation of modules through a web-based interface accessible through the administration area of a Magento installation. Modules are hosted on the Magento eCommerce website as a PEAR server. Any community member can upload a module through the website and is made available once confirmed by a member of the Magento team. Modules are installed by entering a module key, available on the module page, into the web based interface.

There are three categories of modules hosted on Magento Connect:

► Core Modules
► Community Modules
► Commercial Modules

Core and Community modules can be installed via the administration area. Commercial module pages provide price information and a link to an external website.
