Activating The Donation Button with Paypal

Is the code already in place to activate the donation button anywere in the Admin Section? In other words, if everything is already setup on PayPal's end, is everything set up on Composer's end to successfully be able to place proper codes in their repsective places?

Not sure on this, but you could easily add the donate code to a Comcode page or in a custom version of a template without too much trouble (or so I would think). I know there is code for PayPal as a payment gateway, but not sure whether it is implemented to handle donations. Not read anywhere that it is anyway.
