Works GREAT man!
Only problem I had is that both my categorybackcolor and my tableheadbgcolor are the same.
So at first I thought it wasnt blinking (cuz they were the same)
So like before anyone starts to say it doesnt work, try using THIS as your JS to test it:

<script language="JavaScript">
<!-- Begin
$pmblink pmBox.bgColor='#1D6AA0';
$pmblink setInterval("Timer()", 500);
$pmblink x=1;
 function Timer() {		x=1;
		set=0;
	}
	if(x==1 && set==1) {
		pmBox.bgColor='{*categorybackcolor*}';
	set=1;
	if(x==0 && set==1) {
		pmBox.bgColor='#336D95';

		x=0;
		set=0;
	}
}
// End -->
</script>

stick that in the end of forumhome_pmloggedin, REMOVE! the ** from {*categorybackcolor*} and send yourself a PM, and if it doesnt blink then, you probolly did something wrong.
