using phpmyadmin add this query.

this will add the component to the backend list too

INSERT INTO jos_components (name, link, admin_menu_link, admin_menu_alt, ‘option’, admin_menu_img, params) VALUES (‘Reviews’, ‘option=com_reviews’, ‘option=com_reviews’, ‘Manage Reviews’, ‘com_reviews’, ‘js/ThemeOffice/component.png’, ”);

Kinda cheesy but there is no direct way to disable tips on the site.

to remove tips you have to delete the current sentence from the document you want
JHTML::_(‘behavior.tooltip’);

now to remove tips from edit icons go to

component\com_content\helpers\icon.php and remove the JHTML::_(‘behavior.tooltip’); from there
