I have 2 accounts on my computer running Tiger 4.1. One is for me and the other for my wife. I just gave my wife access/permissions to my pictures folder because I want to be able to share pictures and when I changed the "groups" field to include her, I had a drop list list of about 20 different names that I do not recognize. Where could these be coming from? There have been no user accounts set up with these strange names. Looks like someone has been trying to access my computer but not sure...Any ideas? Could this be a firewall issue?
