Notes:
In case you are using the textarea mChat modification, you need to figure out the exact edits yourself, basically the following changes are required:

<!-- IF MCHAT_MESSAGE_LNGTH neq 0 -->
<input type="hidden" name="maxlength" value="{MCHAT_MESSAGE_LNGTH}" />
<script type="text/javascript">
// <![CDATA[
$('textarea.limited').maxlength({
'feedback' : '.charsLeft',
'useInput' : true
});
// ]]>
</script>
<!-- ENDIF -->

plus you DO NOT need to add the following to the message textarea:
<!-- IF MCHAT_MESSAGE_LNGTH neq 0 --> maxlength="{MCHAT_MESSAGE_LNGTH}"<!-- ENDIF -->

Enjoy!
