This extension was very implement and configure. I hit a bit of a snag when Tags kept linking only to my site's homepage - but then I realized that I had unthinkingly installed and activated both the sef404 and TagSef plugins. Once I deleted the TagSef plugin - everything worked just fine.

I love this plugin. It integrates nicely. I'm glad to have finally found a bookmarking plugin that works properly with Joomla!
There is only 1 major problem. I cannot access my site using Internet Explorer 6 if this plugin is active. Anyone using IE6 to access my site gets that weird pop-up error window that says "Internet Explorer cannot open the internet site. Operation aborted."
By the way, I get the same error if I try to get to http://www.wijiti.com usign IE6.

This is a great mod - but there doesn't seem to be any support for it... :(
