For security purposes, access to the directory is a two-step process. In order to view the directory you must first REGISTER for the site. Only after you have been registered and approved will you be able to enter your profile and see the website's entire secured directory. (To do this you must LOGIN on the top, right-hand corner, and click on DIRECTORY, and ADD DIRECTORY ITEM to finalize your profile.) This may seem redundant, however it is done to prevent email abuse and protect privacy.
Registered users that have not completed the step above will receive all email communications, however they will not be able to view the directory.
