The Dink Network

Looks mostly o.k. to me. Um.. if you int &karl on one line you don't need "Int" when you create_sprite. Or just int&karl= creat... on one line. (you only need to int a var once.) Usually when you start a talk () its nice to freeze both sprites otherwise they wander around while talking (remember to unfreeze ).
Is this script going to be attached to &karl. As written it seems to be on another (&karl isn't there yet).
