There's really no need for a members list, when we have google. For example, if you google "sillywizard" and "zealot", some of the top hits are for posts I have made here, and I have made very few. Given that, you can link back to the post, click on the name, and voila!. You are ready to send a private message, if you like.
If you are curious about the admins, go to
http://www.zealot.com/latest_posts.php
and off to the left you will see a list of all the registered users online. The admins come up in red; I have only seen "sanjay" and "maico_shark" in my short time here.
Given that most of us have rather distinctive usernames, and re-use them on various sites, google will also lead you to their other homes. Some members I wanted to contact here, who weren't answering their PM's, I have been able to track down to their youtube page, their deviantart page, their camaro forum, etc.
The internet is really cool, and you can work around almost any inconvenience.
