customer relationships

Hello,

I'm new to Red Hen, and I have had a lot of experience with CiviCRM, but I am ready to jump into the Red Hen flock (I raise chickens too, so it's a good match). Enough of that.

I hope someone can help me with the following flow: A new user signs up. During registration, RedHen contact info is collected. One piece that is also collected is, using check boxes, s/he can select one or more organizations that s/he is affiliated with, and that already exist as organizations in RedHen.
