Mikey - You can achieve your desired result by using a server variable. Here's how I did it in PHP.
1. create a variable at the top of the social module code:
$currentpage = str_replace ("/", "", $_SERVER["REQUEST_URI"]);
2. use this variable as the link in the WA plugin.
This is working well for me and I hope it helps you out too! You can also use $_SERVER["PHP_SELF"] if you do not have dynamic URL strings. Some of my pages do so I use the code in step #1 above.
