I posted this under Bugs and Issues but this might be a better spot, so double posting.
When I paste in the HTML for the non-hosted sign-up form everything works–except there's no Submit Button for the reader to submit their info on the form. I see it in the HTML (at least I think I do). It's in here, right?
<div class="pull-right"><input type="submit" class="btn btn-primary btn-flat" name="yt0" value="Subscribe"/></div>
