Hi!
The group is Los Ninos de Nuestros de Corazones. Their website is
http://lnnc-il-us.org/.
They seem to have events about every-other month. It looks like it depends on someone(s) being willing to put an event together. I've heard great things about the group. We haven't attended anything yet as I just don't feel up to being around that many adoptive families until our little one is home. But we definitely plan on joining in once he's home.
Hopefully we'll see you there some day!
