gravity forms to subscribe and later unsubscribe from multiple choices

One of my websites has multiple newsletters that a user can register for. Basically setting the site up to send post_type rss feeds to mailchimp using 1.4beta.

What I am trying to figure out is how to set up a form where the user can choose from the available feeds to receive, but also have the ability later to go in and remove a choice.

I've tried explaining to a few people that they can unsubscribe via the mailchimp newsletter footer, but that is not going over to well.

Seems like a simple concept that works in other platforms than wp which I use, but can't seem to get a handle on with gravity.

any pointers?

btw
loving the integration. I am not noticing any problems in basic 1.4 configurations using 3.0beta2. Then again, I am only using simple logic at the moment.

Thanks Carl
I had figured out the idea about using the check boxes for subscribing. Where I got 'lost' was having an area where the user could go and see their current subscriptions and remove themselves.

Glad to hear it's something being considered in the future.

I plan on really running 1.4 through it's paces this weekend and filling as detailed a report as I can. I don't see a beta forum here, so not sure where it's best to do any reporting. I know you sent it to me a very long time ago, and I apologize for not getting back sooner. It's taken me this long to become completely competent with wp, where I could file meaningful reports. I've spent months working on wp code now, so at least any input I give would be relevent. So far, I have to say that it works pretty darned good.

lol, ok thanks for the headsup. I'm guessing that you are probably already way beyond where I would have been. If you need more testers just let me know. I love gravityforms and would love to help anywhere I can. It's hands down one of my favorite all time plugins.
