Membership Plugin and My-Theme-Login

Hey,

I'm trying to setup the membership plugin, and everything is pretty much going great. I've also added my-theme-login plugin to setup a redirect, and I'd like to use the custom email responses included with that.

That's where I'm stuck though.

If I setup the 'forgot password' form in my-theme-login, it works fine - the user gets sent the customised form. However, when a new user signs up through the membership plugin, they only get sent the default wp new user email (not the nice custom one from my-theme-login).

Is that a known issue with using these two plugins together? Or am I doing something wrong somewhere?
