I'm so glad you brought this up! I've tried opening two windows, but with msn everytime I do it messes up the first window when I log into the second. My daughter will be thrilled to hear how to be able to have her two characters talk to and trade with each other. She tried before, but had to do it on two different computers and one was upstairs and the other downstairs. She kept running up and down the stairs. She finally gave up and told me it was just too tiring to have them talk to each other
