Simple signup box feature request

I would totally love if there was an easy way to put a signup box anywhere I wanted on my sites that was integrated with e-Newsletter. Currently there's a widget, and that's great, but what if I have an under construction page that's super simple html like this one:

http://www.homebodybotanicals.com

For this, I signed up for a free account at tinyletter.com for their sign-up box, and when the site is finished I'll import the contacts from the tinyletter account into the e-Newsletter plugin... But it'd be really nice to be able to do this right from the plugin.

Unless I'm missing something and there's already a way to do it?

Thanks in advance!
