Include mailing list signup form on custom home page

Hello,

I am using the technique outlined on this page to employ a custom home page that is separate from the main Word Press installation. It works as advertisted:

I am also using this mailing list plug-in:

Now. what I would like to do is include the mailing list signup form on my custom home page.

I followed the instructions here, which describe how to call WordPress content from outside WordPress:

https://www.voodish.co.uk/articles/display-wordpress-content-from-outside-wordpress/

I can get the example code to work, but I am unable to figure out how to include the mailing list form.

The standard way to do the include – using <!–mail_sign_up–> – obviously doesn’t work, since the custome home page is not a regular WP page.

I also tried including the whole maillist_v1.php page but nothing showed up when I did that.

I’m stuck, but imagine the solution can’t be that difficult – anyone have any ideas?

Thanks in advance,
