Where are my emails sent to?

You need to be more specific. Where does that form come from ?

Do you use a plugin ?

I am using G-Lock optin. I am having troubles setting it up properly. Can you help me?

If so, you should ask here: https://www.justlan.com/forum/viewforum.php?f=24

Please note, many plugins have similar names. It greatly helps everyone if you can link to them.
