+Instructions:
+
+Load the plugin using:
+
+ 	$this->load->plugin('captcha');
+
+Once loaded you can generate a captcha like this:
+	
+	$vals = array(
+					'word'		 => 'Random word',
+					'img_path'	 => './captcha/',
+					'img_url'	 => 'http://example.com/captcha/',
+					'font_path'	 => './system/fonts/texb.ttf',
+					'img_width'	 => '150',
+					'img_height' => 30,
+					'expiration' => 7200
+				);
+	
+	$cap = create_captcha($vals);
+	echo $cap['image'];
+	
+
+NOTES:
+	
+	The captcha function requires the GD image library.
+	
+	Only the img_path and img_url are required.
+	
+	If a "word" is not supplied, the function will generate a random
+	ASCII string.  You might put together your own word library that
+	you can draw randomly from.
+	
+	If you do not specify a path to a TRUE TYPE font, the native ugly GD
+	font will be used.
+	
+	The "captcha" folder must be writable (666, or 777)
+	
+	The "expiration" (in seconds) signifies how long an image will
+	remain in the captcha folder before it will be deleted.  The default
+	is two hours.
+
+RETURNED DATA
+
+The create_captcha() function returns an associative array with this data:
+
+  [array]
+  (
+	'image' => IMAGE TAG
+	'time'	=> TIMESTAMP (in microtime)
+	'word'	=> CAPTCHA WORD
+  )
+
+The "image" is the actual image tag:
+<img src="http://example.com/captcha/12345.jpg" width="140" height="50" />
+
+The "time" is the micro timestamp used as the image name without the file
+extension.  It will be a number like this:  1139612155.3422
+
+The "word" is the word that appears in the captcha image, which if not
+supplied to the function, will be a random string.
+
+
+ADDING A DATABASE
+
+In order for the captcha function to prevent someone from posting, you will need
+to add the information returned from create_captcha() function to your database.
+Then, when the data from the form is submitted by the user you will need to verify
+that the data exists in the database and has not expired.
+
+Here is a table prototype:
+
+	CREATE TABLE captcha (
+	 captcha_id bigint(13) unsigned NOT NULL auto_increment,
+	 captcha_time int(10) unsigned NOT NULL,
+	 ip_address varchar(16) default '0' NOT NULL,
+	 word varchar(20) NOT NULL,
+	 PRIMARY KEY `captcha_id` (`captcha_id`),
+	 KEY `word` (`word`)
+	)
+
+
+Here is an example of usage with a DB.
+
+On the page where the captcha will be shown you'll have something like this:
+
+	$this->load->plugin('captcha');
+	$vals = array(
+					'img_path'	 => './captcha/',
+					'img_url'	 => 'http://example.com/captcha/'
+				);
+	
+	$cap = create_captcha($vals);
+
+	$data = array(
+					'captcha_id'	=> '',
+					'captcha_time'	=> $cap['time'],
+					'ip_address'	=> $this->input->ip_address(),
+					'word'			=> $cap['word']
+				);
+
+	$query = $this->db->insert_string('captcha', $data);
+	$this->db->query($query);
+		
+	echo 'Submit the word you see below:';
+	echo $cap['image'];
+	echo '<input type="text" name="captcha" value="" />';
+
+
+Then, on the page that accepts the submission you'll have something like this:
+
+	// First, delete old captchas
+	$expiration = time()-7200; // Two hour limit
+	$DB->query("DELETE FROM captcha WHERE captcha_time < ".$expiration);		
+
+	// Then see if a captcha exists:
+	$sql = "SELECT COUNT(*) AS count FROM captcha WHERE word = ? AND ip_address = ? AND date > ?";
+	$binds = array($_POST['captcha'], $this->input->ip_address(), $expiration);
+	$query = $this->db->query($sql, $binds);
+	$row = $query->row();
+
+	if ($row->count == 0)
+	{
+		echo "You must submit the word that appears in the image";
+	}

+/*
+Instructions:
+
+Load the plugin using:
+
+ 	$this->load->plugin('js_calendar');
+
+Once loaded you'll add the calendar script to the <head> of your page like this:
+
+<?php echo js_calendar_script('my_form');  ?>
+
+The above function will be passed the name of your form.
+
+Then to show the actual calendar you'll do this:
+
+<?php echo js_calendar_write('entry_date', time(), true);?>
+<form name="my_form">
+<input type="text" name="entry_date" value="" onblur="update_calendar(this.name, this.value);" />
+<p><a href="javascript:void(0);" onClick="set_to_time('entry_date', '<?php echo time();?>')" >Today</a></p>
+</form>
+
+
+Note:  The first parameter is the name of the field containing your date, the second parameter contains the "now" time,
+and the third tells the calendar whether to highlight the current day or not.
+
+Lastly, you'll need some CSS for your calendar:
+
