Getting Started with Dreamwidth

I've set up[ a comm. I've set myself up as mod/administrator. I've set up my email to receive notifications. I've set up a co-mod with administrator privileges. So far, so good.

How do I set up email notifications for both me and my co-mod? Can I do that, or does my co-mod need to do it?

I've seen instructions in the FAQ for how to set up as a solo mod, pass all the modly duties on when you want to give up modding, but not how to share modding duties. Please help!
