[Miniature-Giant]

Hm, could someone please clue me in a bit?

I have downloaded, installed, edited, etc., etc., and think that I have the module "working". But...
How do I tell, am I supposed to do something else to "use' it, e.g., do I need to remake my "HTML catalog"? Should I see a change in the urls in the address bar when I surf my site and click on products, etc.
Perhaps someone can point me toward a doc that describes what this does, etc. -- sorry to be so dense on this subject. I'm just not that familiar with some of these SEO tools and nominclature.

Thanks!
James
