<if condition="$vboptions['lppaktiv']">
<if condition="$userinfo['lppstatus']=='1'">
<a onClick="window.open('lpp_messenger.php?do=lppmessenger&amp;userid=$userinfo[userid]','_blank','toolbar=no,resizable=yes, location=no,menubar=no,width=430,height=310,top=15 0,left=100,status=no');return false"
target="_blank" href="lpp_messenger.php?do=lppmessenger&amp;userid =$userinfo[userid]">
<img src="$stylevar[imgdir_misc]/vbim.gif" alt="$userinfo[username] $vbphrase[lppmess_send_a_mess]" border="0" /></a></span>
</if>
</if>
<!--LPP Messanger Stop-->
