Hello toddmcm,
Thanks for your patience! We do a full forum pass every 24-48 hours. Sorry for the slight delay, we were a bit busier with the release of 3.6.
As of right now, only admins have the ability to view the attendees list. (I believe the rationale has something to do with the edit_posts capability, and some sort of programming difficulty in getting around that)
If you have a moment, we’d love for you to submit your idea to our UserVoice forum. We take user ideas and contributions very seriously, and many times their ideas end up in our future releases.
I will make a ticket for this feature request, and update this thread if we ever release a solution for this problem. It does seem like a very good idea!
Sorry I wasn’t able to give you a better answer!
Cheers!
