Released by Cerulean Studios, Trillian 0.73 is an instant messaging tool that serves as a one-stop portal for all chat traffic. This handy tool imports chat specifics (such as passwords, buddy lists, and client preferences) into a single interface and allows users to simultaneously connect with five Internet chat engines: Yahoo Messenger, MSN Messenger, ICQ, mIRC, and AIM. An updated version from Trillian 0.725, version 0.73 includes "bug fixes and other minor enhancements" that offers a smoother connection and a better relationship between and among the five chat engines. This software is free for noncommercial use and requires Windows 95/98/Me/NT/2000/XP.
