Aweber Integration?

[TurkeyFish]

When a user registers or checks out, I'd like to automatically add them to my AWeber list if the opt-in checkbox is checked. 

 

I can't find a module to do this. How might I go about editing the code?

you can try with a module hooking to

actionCustomerAccountAdd

It will have 'newCustomer' and '_POST' as $params entries, so you can use  Aweber's webservice (if they have any) in the module, and send over the information according to the api (hard to guide you further, it's too specific)
