Hi

Can some one please summery this please, or direct me to the where or what is the final thought on this mod.
The are 100s pages in few Threads some say it not good for Google as it will make you loose ranking, also I see the are different version of this mod, which one will suit my Zen cart, I use Zen 1.3.7

P.S when I refresh my page I get better looking url, is that normal ?
Thank you
