It has never been on the official site as far as i know? The official site is
http://messenger.msn.com/ or
http://www.msnmessenger-download.com/ if you wish. I never saw 6.2 there.
You probally are talking about msn-int.com which is
not the official MSN site. It
is owned by Microsoft, but they seem to use it as some kind of test site. It's not ment for public use, i think Microsoft should restrict IP access on that whole domain to keep people from getting confused about it
.
