This modification does indeed work.
You just left a portion of information out, or rather "phrased" it incorrectly.
Instead of
Code:
http://yoursite.com/yourforumdir/misc.php?do=page&template=Affiliates
Insert:
Code:
http://yoursite.com/yourforumdir/misc.php?do=page&template=Affiliate
Without the "s" at the end and then you will get the page you are looking for.
You are basically calling for the wrong template each time because of the template name confusion.
Nice job by the way, I love this quick Mod.
Please do edit the last line in your opening post to inform readers.
