msn trouble

please can some 1 tell me if im signed in to msn?

Barry set up his own msn and i dont know what he has done lol
i know have 2 1 that i can see and another that i cant lol
Samantha was on the net today and i always make sure that Msn is off when she is on but some 1 started chatting to her that i did not want her chatting to. so i have now taken it off my pc (will put it back on as soon as i sort it out) but i need some 1 to let me know if i am signed in or not
