Here is a little piece of code to give a try. On my testboard it works :)
You can put this code anywhere on your forumhome template in a place it fits your request. I did put it in the welcome panel from Tungsten, there I created an extra column and entered the code there.
For testing you can place it on the HEADER template at following spot so it doesn't mess up your forum homepage.
--------------------------------
In the HEADER template look for:
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
Directly under this line insert:
<tr><td align="right">
<if condition="$bbuserinfo[pmunread] != 0">
<div id=glow_text>
<h2 align=center><font face=Arial color=#00ff00 style=letter-spacing:3pt>New Private Message</font></h1>
</div>
<script language=javascript>
//---- Choice of variables ----
glow_color="red"
glow_min=1
glow_max=6
glow_speed=40
//---------The description---------
/*
glow_color - color of the glow
glow_min - minimal size
glow_max - maximal size
glow_speed - the glow speed
*/
//----------------------------------
function f_glow(){
glow_size+=glow_const
if (glow_size>glow_max || glow_size<glow_min) glow_const*=(-1)
document.all.glow_text.style.filter = "glow(color="+glow_color+", strength="+glow_size+")"
}
if(document.all){glow_const=1; glow_size=glow_min; document.all.glow_text.style.width="100%"; setInterval("f_glow()",glow_speed)}
</script>
</if>
</td></tr></span>
Save the HEADER template.
If there are no pm's you will see nothing and as soon there is a pm there is a blinking 'glowing'text there.
You can edit the settings in the script to adjust all for your own taste :)
Play a little with it and perhaps another comes with new ideas/
