I'm assuming you are talking about the Private Messenger service from FaithWriters.
Log on to your account at FaithWriters:http://www.faithwriters.com/myaccount.php
Once you log on with your FaithWriters member account (which may not be the same as the one you used here), you will be taken to your account page:http://www.faithwriters.com/myaccount/m ... t-main.php
As a Platinum 500 member, your private messages are definitely available to you. You'll see the box with the yellow header near the top of the page. It says: Private Messenger - stay connected.
Under that heading you'll see a link that should say how many private messages you have waiting for you. Something like "You have 2 new messages." Click on that link.
That will take you to another page, and from there you just click on the "View Messages" yellow button. You will be taken straight to the list of private messages waiting for you.
I think once you see the private messenger box right at the top of your account page, you'll realize you may have been looking in the wrong spot? Perhaps?
I've got nothing to do with the site design, but it is a big site and I agree it can be quite confusing to new members who aren't familiar with the layout. There is a search option on your account page now, which can be VERY helpful (it's the Google powered search box under the Quick Links heading on the right side of your account page).
So give it a try and let us know how you go. If you hit any problems, just call for help again. We're happy to try and point you in the right direction.
