Find:

<input type="submit" id="qr_submit" class="userprof_button" value="{vb:rawphrase post_message}" name="sbutton" accesskey="s" onclick="clickedelm = this.value" tabindex="1" />

On a side note, you couldn't find vB_ProfileBlock_VisitorMessaging because it extends vB_ProfileBlock, and "vB_ProfileBlock_$class" is used to fetch the appropriate class.

Thank you Yellow Slider. Yes, I did know that the template in use is memberinfo_block_visitormessaging as it is exactly in that template that I intend to put the hook!

Thanks.
