Sorry vB 3.0.3
Code:
// in your NAVBAR template find //
<if condition="$bbuserinfo['userid']">
<td class="alt2" valign="top" nowrap="nowrap">
// Right under that add //
<if condition="$bbuserinfo['pmunread']">
<phrase 1="<font id=blink>$vbphrase[unread_x_nav_compiled]</font>" 2="$vbphrase[total_x_nav_compiled]" 3="$session[sessionurl]">$vbphrase[private_messages_nav]</phrase>
<script>
document.all.blink.style.color = off_color;
setInterval("blink()",blinkspeed);
</script><br>
<else />
<phrase 1="$vbphrase[unread_x_nav_compiled]" 2="$vbphrase[total_x_nav_compiled]" 3="$session[sessionurl]">$vbphrase[private_messages_nav]</phrase><br></if>
// all done //
