Tiny MSN Messenger clone. You will log in as Invisible, so no one will notice youТ‘re online. Then, if you decide you want to talk, get out of Invisible mode and start chatting, or just switch to Messenger itself.It consists of a small executable file and nothing else. Nothing is written to your hard disk, nothing is stored in your registry. ItТ‘s perfect for carrying on a floppy disk or an USB drive!
