Mail Chimp Sign Up

[whiskymac]

Hey everyone, Hope your all well :)

I was wondering if anyone could point me in the right direction - At the moment im using mail chimp to host my email list however, Im hosting competitions on a daily/weekly basis & was wondering how i would get mailchimp to display a agree to terms & privacy policy button and then once the customer ticks those boxes adding in a Enter competition box to submit like this one...



Also i was wondering if the subscriber has already joined the my list & want to enter the comp can they still do this or will it come up as they have already joined the newsletter? if this is so is there any other way of creating a email list form that would allow me to do all of this?

Thanks.
