Hi, welcome to the forums, and no sorry, there's no such thing... contacts are in your MSN server, so you don't need to import contacts, they'll already be in there, and about logs, sorry, there is no converter...
But if I remember correctly, Trillian was only using simple .txt files for logs, right? in that case, you can just go to your amsn log directory (if you took the time to write more info, like which operating system you use, i'd tell you where it is.. otherwise, look it up in the http://amsn-project.net/faq.php
) create a Trillian directory, and put all your trillian logs in there... make sure the filenames are being "firstname.lastname@example.org
" so for example "email@example.com
Then in amsn, when you go to see your contact's logs, in the combobox for the date, you'll get a new "Trillian" section to read the trillian logs. They should appear as normal text in there.
