Ayttm is an instant messaging (aka chat) client that provides all-in-one chat functionality for several major instant messaging services from one simple program. Ayttm "Contacts" allow you to refer to several accounts of the same person from a single contact name, making it one of the cleanest and simplest clients to use. It features support for file transfers, group chat, MSN GnomeMeeting integration, tabbed chat, smiley themes, status tooltips, conversation logging, automatic translation, GPG signing/encryption, typing notifications, spell checking and import of contacts from other clients.
The meaning of Ayttm is "Are you talking to me?" and the software name is pronounced as either "Ay-wai-tee-tee-em" or "item".
