This product seems to only contact PGP.com's own public keyservers. It does not allow one to post public keys to any other server; does not allow one to query other public keyservers for someone else's public key; does not allow export of public key to ascii for manual placement on other public keyservers. The online Help files tell how to do the functions, but the application does not have the functions the Help file says it has. These are serious and severe restrictions, as they limit the user to staying totally within the PGP.com universe. I would call this completely a show-stopper for the use of the application.
