I'm trying to test my newsletters

I feel bad about asking this because I should probably know but I can't search the answer on the forum without getting too many threads. I want to test my newsletters so I need to send one only to the Administrator group. How can I edit who is part of that group? It says I have one administrator already but I don't even know who that is.

The one admin would be you at whatever email address you specified when you set Zencart up. That's probably where you want to send your test.

The problem is that I didn't set zen-cart up because the website already existed before I worked on it. I would need to know where to make change and/or add someone to the list.

Admin - Tools - Admin Settings

You can reset the admin email address there.

I knew that section already but we have thirteen administrators, most of them with e-mails, and the newsletter says we only have one, so I don't know.
