Many of us find this plugin too difficult to install and configure. For very technically proficient users of WP, it is great. But for the vast majority of us it is beyond our capabilities. One person who I know and would consider quite advanced technically did install and configure it but claimed it took him 4 hours to get it correct and was the hardest install of a WP plugin he had ever done.

Maybe the intended user base for the plugin does not include non-tech types or it just may not be possible to simplify, but it would sure be great if there was an easier way to install and use it!
