Hi,

Open vShare/templates/admin/settings.tpl file and find first,
Code:
<a href="http://labs.buyscripts.in/projects/vshare/wiki/List_Per_Page" target="_blank"><img src="{$img_css_url}/images/help.png" alt="help" /></a>
then, replace it with
Code:
<a href="http://labs.buyscripts.in/projects/vshare/wiki/Admin_Email" target="_blank"><img src="{$img_css_url}/images/help.png" alt="help" /></a>
