auto-join new users to outside email list

[polarize]

I would like to add anyone who signs up for a forum account to my company's email list automatically.

Our email list company has an API for this, which basically involves submitting a GET request to a url.

Is there a built-in way or a plugin that does this? Seems like it would be a common thing.

anyone have any insight on this?

Just do whatever you have to do in the register_addmember_complete hook.
