MSN messenger last login time and date

Hello friends,
I am using MSN messenger 7. Can anyone help me to find out my friends last login time and date on messenger?

All suggestions are welcome.

Enable view of hidden files and folders (folder options) then go to C:\Documents and Settings\username\msn\Contacts\.....@hotmail.com.
This folder shows you the contact information of your MSN-contacts, i.e. their names and extra added sentences. If you are lucky, one of your contacts has changed their name since the last time you logged in and the intruder logs in, so if you check the "modified-date" you can filter till you find a "modified-date"
