The IM (instant messaging) gateway plugin allows users to log in to and communicate through other instant messaging services via their Jabber accounts.
Copy the gateway.jar into the plugins directory of your Wildfire installation. The plugin will then be automatically deployed. To upgrade to a new version, copy the new gateway.jar file over the existing file.
By default, after the plugin has been deployed all of its features are disabled. This plugin is configured via the "IM Gateway" sidebar item located under the "System" tab in the Wildfire Admin Console.
