First of all, ACKNOWLEDGEMENTS
All that I made was to do some simple and small changes in the code developed by Kymation. All credits goes for him.
This addon adds an About Us link to your store's Navigation Bar.
Why? Trust is basic (a must I think) for customers in ecommerce. They want to know who is at the other side before paying anything.
This Addon requires the Modular Navigation Bar Addon to function. Get it here: http://addons.oscommerce.com/info/9440
Obviously, it also requires an About Us page installed on your OsCommerce site. I.e., you can do it with this addon: Extra pages-info box w/ admin for OSC2.3 (http://addons.oscommerce.com/info/8490)
Also, if you have installed IMPROVED CONTENT MODULES ADMIN FOR 2.3.4 RESPONSIVE, it is ready for disable/enable function. You can download it here: http://addons.oscommerce.com/info/9458
