<?php

// Add the following to your functions.php file.
function tribe_filter_before_html_field( $field ) {
	echo '<fieldset id="tribe-field-tribeEventsBeforeHTML" class="tribe-field tribe-field-textarea tribe-size-large">';
	echo '<legend class="tribe-field-label">Add HTML before calendar</legend><div class="tribe-field-wrap">';
	wp_editor( tribe_get_option('tribeEventsBeforeHTML', ''), 'tribeEventsBeforeHTML', array( 'teeny' => true ) );
	echo '</fieldset>';
}	

function tribe_filter_after_html_field( $field ) {
	echo '<fieldset id="tribe-field-tribeEventsAfterHTML" class="tribe-field tribe-field-textarea tribe-size-large">';
	echo '<legend class="tribe-field-label">Add HTML after calendar</legend><div class="tribe-field-wrap">';
	wp_editor( tribe_get_option('tribeEventsAfterHTML', ''), 'tribeEventsAfterHTML', array( 'teeny' => true ) );
	echo '</fieldset>';
}	

add_filter( 'tribe_field_output_textarea_tribeEventsBeforeHTML', 'tribe_filter_before_html_field' );
add_filter( 'tribe_field_output_textarea_tribeEventsAfterHTML', 'tribe_filter_after_html_field' );

Also trying to solve this short code issue. Any guesses?
