JB,
Most likely you can use your email service, but you’ll have modify the theme just a bit to do so.
1) Go to the appearance section and select edit to open up the theme editor.
2) From the list of files on your right, choose newsletter.php
3) You’ll need to replace the content below (it pretty much the entire file) with the sign up code for your service:
4) Save your changes.
That should swap out MailChimp for your newsletter service.
Here’s how to change the copyright.
1) In the theme editor, open up the footer.php file.
2) Replace this:
<a href=”<?php echo home_url(); ?>/”>© <?php echo date(‘Y’); ?> <?php bloginfo(‘name’); ?></a><br /><a href=”http://www.organizedthemes.com”>Organized Themes</a>
with whatever text you’d like to go there.
3) Save your changes.
That will change the copyright notice for you.
If you have any questions, let me know.
