Email cloaking doesn't work when there are tags inside of an <a> tag containing a mailto: link. Instead of disabling the email protection site wide, you could just add something like this where you want to have a linkable email address and keep the extra inner tags:
<script type="text/javascript">
var emailLink = "mailto:" + "glicksmank" + "@" + "catholicdioceseofwichita.org";
document.getElementById('frkemailsignup').href = emailLink;
</script>This would be placed after said tag, so it would look like this:
<p><a id="frkemailsignup" href=""><span class="readon"><span>Sign up!</span></span></a></p>
<script type="text/javascript">
var emailLink = "mailto:" + "glicksmank" + "@" + "catholicdioceseofwichita.org";
document.getElementById('frkemailsignup').href = emailLink;
</script>turn off my editor to paste this script into the article. Otherwise, it was stripped out when I saved the article.
