TerraIM is an instant messaging client that connects to the AOL Instant Messenger network. Thus, one can use TerraIM with an existing AIM, ICQ, or AOL screen name. Just log in using your AIM screen name or ICQ number with TerraIM, and your regular buddy list will show up. It adds on several useful features such as offline messaging, tabbing, aliasing, remote control and logging, but currently lacks certain features such as buddy icons and Direct IM. Download the EXE file to a folder of your choice. Launch TerraIM_1.2.1.exe.
