Magento Core Functions and Classes EmailNotify is overriding

Euvat is overriding some Magento Core Classes. So when experiencing conflicts with other Extensions, or having lost store customizations with EmailNotify being installed, these are the Classes EmailNotify is overriding from the Magento Core:

Magento Core Class	by EmailNotify rewritten to	Remarks
`none`	`none`	EmailNotify uses a Observer to Onepage Checkout.

In case of Magento Core classes overridden by other extensions, or own customizations, be aware that you might need to consolidate these changes into one of these classes. To keep the EmailNotify functionality in such case.
