<script>
function smf_page_v1(link,title,content){
//Created by Agent Moose (smcodes.smfforfree3.com)
if(location.href.match("action="+link)){
document.title=""+title+"";
$("#bodyarea").hide()
$("#bodyarea").before("<div class='tborder'><div class='catbg' style='padding: 6px; vertical-align: middle; text-align: center; '>"+title+"</div><div id='upshrinkHeaderIC'><table border='0' width='100%' cellspacing='1' cellpadding='4' class='bordercolor'><tr><td class='windowbg2' width='100%'>"+content+"</td></tr></table></div></div>")
};};
