         * - format_callback : is the format callback to use to build your plugin's activity action
         * - label : is your plugin's front end dropdown option label
         * 
         * - context : is an array of the contexts your plugin's dropdown option should show
         *              - activity      > the Activity directory page
         *              - member        > the user's activity profile pages

         *      Using context can avoid using the front-end dropdown hooks such as bp_activity_filter_options. Although, it's possible
         *      some themes didn't upgraded to BuddyPress 2.1 way of displaying new activity types in front end dropdowns.
         *      So you might check if bp_activity_show_filters() function exists to be sure of it
         *      
         * - track : whether to record or not an activity for your plugin
         * - publish_callback (optional) : your specific callback if you want to have more control on the way activities will be recorded
         * - unpublish_callback (optional) : your specific callback if you want to have more control on the way activities will be removed
         * - update_callback (optional) : your specific callback if you want to have more control on the way activities will be updated
         * - untrash_callback (optional) : your specific callback if you want to have more control on the way activities will be reverted
         * - remove_callback (optional) : your specific callback if you want to have more control on the way activities will be removed
         * 
         * NB : your plugin's post type will only be tracked if the BuddyPress blogs component is active, as your plugin's post type will
         * be attached to the BuddyPress blogs component one (post) and the activity will be recorded on multisite child blogs if the discourage
         * search engines settings is not set.
