Wow, thanks swguy, this looks like a great contribution!

I'd really like to replace zen cart's default newsletter functions with all the benefits from mail chimp.

However, what I really need to use, is the "group" function of mailchimp. I really need to give my customers the option to chose which subjects they'd like to receive newsletters about. When I read the pre-installation instructions of swguy's module, I read this

"In your Sign-up form, I suggest only having email address; if you want more fields, you'll have to modify this contribution."

I suppose this means that if I'm gonna use the group function, I'd need to modify this contribution?

Please clarify this. I'm not a coder, but I'm definately up for hiring someone if I need to. Thanks
