I regularly chat in Chinese between IM conversations with my Singapore friends on Windows Live Messenger. Previously, I had some difficulties typing in Han characters (Chinese) and many can attest to my woeful Hanyu Pingyin.
With the release of the new English-Chinese Bilingual Dictionary Agent from the Natural Language Computing group, now I have access to bilingual dictionary within my IM client. To add this functionaility to your Live Messenger, just add ‘firstname.lastname@example.org’ to your list of online contacts.
