Contact Form Data Emailing

I am using following code on my HTML contact form to make it possible for ppl to contact me through private msgs. But now I want the data to be emailed instead of private msgs.

Can someone on here please suggest the changes that I would require in the following code to achieve this?

Thanks!

Code:

<form enctype="multipart/form-data" onsubmit="return vB_Editor['text_editor'].prepare_submit(0,0)" name="post" method="post" action="/privmsg">
 
<input id="username" class="post" type="hidden" tabindex="1" size="25" value="rustbus" name="username[]" readonly="readonly" style="margin:1px 0" /> <span style="font-family: 'Trebuchet MS'; font-size: 10px;">

<br /><strong>Subject:<span class="obligatory">*</span></strong><br /><input id="acpro_inp10" class="post" type="text" onkeypress="if (event.keyCode==13){return false}" title="Query" tabindex="2" maxlength="72" size="45" value="Forum" name="subject" style="width:100.5%" />

<br />QUERY:<span class="obligatory">*</span></strong><br /><textarea id="text_editor_textarea" class="post" wrap="virtual" tabindex="3" cols="5" rows="3" name="message" style="width:99%"></textarea>

<br /><input type="hidden" value="" name="lt" /> <input type="hidden" value="inbox" name="folder" /> <input type="hidden" value="post" name="mode" /><input class="mainoption" type="submit" accesskey="s" tabindex="6" value="Send" name="post" /><input type="reset" value="Reset" onclick="window.location.href='http://pacvwr.forumstopic.com'" /><br />
</form>

PS: Its a multipart form thus the multipart tag.

No one to help here?
