hmmm.. that's pretty interesting.. I'll bet you both are in the same school as pwaring suggested.. adityaa1's profile.. so you're both from India.. why don't you contact him/her and see how close you two really are.. might be sitting right next to you..hehe..

for now, you both better set it up not use the cookies in your profile and manually log in each time.. or get togther and figure out how to delete the cookies you both have as they must be shared somehow. I don't think there's much that can be done from AO's point of view.
