+The smiley helper is totally awesome. However I found a little bug. On the textarea, the smiley is always inserted at the end of the text. So I suggest this replacement to let the smiley inserted on the cursor position.
+
+Step 1:
+Copy smiley_helper.php from system/helper to system/application/helper, so your replacement won't affect to another installation.
+
+Step 2:
+Replace the function js_insert_smiley with this
+[code]
+function js_insert_smiley($form_name = '', $form_field = '')
+    {
+        return <<<EOF
+[removed]
+    function insert_smiley(id) {
+        id = ' ' + id + ' ';
+        var obj = document.getElementById('{$form_field}');
+        if(typeof(document.selection)!='undefined') 
+        {
+            obj.focus();
+            var range = document.selection.createRange();
+            if(range.parentElement() != obj) {
+                return false;
+            }
+            var orig = obj.value.replace(/rn/g, "n");
+            range.text = id;
+            var actual = tmp = obj.value.replace(/rn/g, "n");
+            for(var diff = 0; diff < orig.length; diff++) {
+                if(orig.charAt(diff) != actual.charAt(diff)) break;
+            }
+            for(var index = 0, start = 0; (tmp = tmp.replace(id, "")) && (index <= diff); index = start + id.length) {
+                start = actual.indexOf(id, index);
+            }
+        } else {
+            var startPos = obj.selectionStart;
+            var endPos = obj.selectionEnd;
+            obj.value = obj.value.substr(0, startPos) + id + obj.value.substr(endPos, obj.value.length);
+        }
+    }
+    
+    // Original insert_smiley function
+    // function insert_smiley (smiley)
+    // {
+    //     document.{$form_name}.{$form_field}.value += " " + smiley;
+    // }
