mmbership – is there a way to manage communications via aweber, mailchimp, etc?

hi,

Is there a way to automatically assign someone to a membership via a signup form in aweber, mailchimp, etc?

also, is there a way to automatically add members to a list on aweber, etc?

I guess my question really is: how do people who use the membership module email market to their members while giving them an option to opt out and comply with spam regs?

I’d be interested in hearing feedback.

thanks!
