Footers:
<script>
function Activity(){
$("td.titlebg:contains(Forum Stats)").parent().next().each(function(){
if(this.innerHTML.match(/(\d+) Posts/i)){
var bPosts = RegExp.$1 + RegExp.$2;
$("tr").each(function(){
if(this.innerHTML.match(/(\d+) Posts/i)){
var fPosts = RegExp.$1;
var Activity = Math.round(100 * fPosts / bPosts);
$(this).find("td.windowbg[valign='middle'] span.smalltext").append("<br>" + Activity + "% Activity");
};});};});};
Activity();
</script>
Here is the code alot of people wanted! The Activity Code, straight from the SMCodes Footers! There is one problem with it though. If you look at your board stats, find (number) Posts.
If that number doesn't have a comma for you, it will work perfectly right when you put it on your forums, but, if you do have a comma, you will need to edit a part of the code.
You will need to add ,(\d+) to the code in this line:
if(this.innerHTML.match(/(\d+) Posts/i)){
Example, if you have 10,000 posts, that line of code would look like this:
if(this.innerHTML.match(/(\d+),(\d+) Posts/i)){
There ya go, might be a little confusion for some of you, but you can try to get it

Enjoy

Note*
Some of my members on my forum have tried this code on there forum and it didn't work, and I don't know why. So if you have that problem, please don't keep on asking about it. Thanks.
