This worked well, i love it

Thanks a lot, i use BuddyPress to manage a bunch of members and this is really great cause i use mailchimp to inform them of stuff.

The only thing i would want added to this is the ability for buddypress users to manage their mailchimp subscription on the buddypress notifications or settings page.

and maybe support for custom post types (or at least wp jobs manager/resume manager) when publishing campaigns.
