They do log ip addresses, times in and out. Every site etc.. has some sort of logging. Even this forum logs ip addresses. Even your isp does it. How do you think riaa, mpaa etc.. bust you. And with the patriot act they dont have to give reasons for anything. They get your ip and call your isp and ask what times was ip xxxx was on and who did the ip belong. Like I said comcast got sued for tacking their customers. I am sure after awhile they trash the data. I never said if they did or didnt log your conversations. CookieRevised was so eager to prove me wrong that CookieRevised didnt read what I said and what them sites said. Usually when someone is so fast to prove someone wrong either they dont know or they hiding something. You could email them or use that link that was given here
http://channel9.msdn.com/ShowPost.aspx?PostID=97906 and call them.
http://privacy1.msn.com/fullnotice.armx is the link. When it come to terrorism and something criminal you can beat they can and probably would record everything you say on messenger and even in chatrooms. And I dont like the idea of msn or anyone else besides me and the people I talk knowing what I said to someone else. Only thing you can do is change messenger that has encryption built in like aim, or get program like I mentioned. And for your email use pgp or gpg.
