+<h4>Option 1 &ndash; Delete Your Profile</h4>
+<p>
+  Utilizing this option will remove your current employment profile and skills. This will preserve any success stories
+  you may have written, and preserves this application&rsquo;s knowledge of you. This is what you want to use if you
+  want to clear out your profile and start again (and remove the current one from others&rsquo; view).

+
+<h4>Option 2 &ndash; Delete Your Account</h4>
+<p>
+  This option will make it like you never visited this site. It will delete your profile, skills, success stories, and
+  account. This is what you want to use if you want to disappear from this application. Clicking the button below
+  <strong>will not</strong> affect your No Agenda Social account in any way; its effects are limited to Jobs, Jobs,
+  Jobs.
+</p>
+<p>
+  <em>
+    (This will not revoke this application&rsquo;s permissions on No Agenda Social; you will have to remove this
+    yourself. The confirmation message has a link where you can do this; once the page loads, find the
+    <strong>Jobs, Jobs, Jobs</strong> entry, and click the <strong>&times; Revoke</strong> link for that entry.)
