I would like to add a horizontal email subscription box to the post and page templates so that I don't have to add it manually in the HTML each time I create a post.
The code is:
<iframe src="http://www.theopenalgorithm.com/forms/horizontalform.html" frameborder="0" scrolling="no" height="" width="500"> </iframe>
How can I add this to the code so that it shows up below my posts and pages?
Thanks for your help in advance.
