How can I add additional clients to a case?
From a comment by Coleman on June 18, 2015 regarding a question at civicrm.stackexchange.com/.../module-or-extension-to-use-for-tracking-agreements

&gt; You can setup CiviCase to enable multiple clients per case, by editing
&gt; your xml/configuration/Settings.xml file. Set
&gt; &lt;AllowMultipleCaseClients&gt;1&lt;/AllowMultipleCaseClients&gt;
