This is a query from Arun Prasath, one of my friends:
How to enable GP users to log on to Personal Data Keeper (PDK). Where the setup needs to be done?
Arun, I have uploaded the Documentation Manual for PDK on Google Docs (An invitation has been sent to your ID), which explains the Installation Setup and Configuration. While I have no clue about what this does, as I am yet to see this product, I would add points to this post, whenever I gain more knowledge on this.
