Ok so here's the deal... i'm trying to find out a few truths and feel a bit guilty for snoopin around. However let's put it this way, why would my boyfriend log onto his msn messenger account and each time have 10 messages ping up asking him to add them as a friend. Bear in mind he has accepted a few and they are genuine people. I also have an msn acct and it doesnt happen to me. Can someone explain the difference?
