I wasn't quite sure what I needed to do to add this in my sidepal, I read the instructions and still wasn't quite sure
I have it working just fine but am not sure about how often it will cache? It was at 30 days by default and I changed it to 5, uploaded again and even though the header (Top 10 active posters in the last 5 days) the post amount didn't, it's been over an hour also. Here is what I did to install it (6.2.3) BTW Great hack!
I opened up sidabarpal.php and added this:
if ($sidebar_include['tenrecent'] == $x && !$xused) {<br /> include "$thispath/pals/custombox1pal.php";<br /> $xused = 1;<br /> }
And then added this near the top:
$sidebar_include['tenrecent'] = "4";
