Net Message 1.6.2
Send messages across the network, using the Windows Messenger Service, without the need for a client install to receive the messages.
The program provides message interception, history of sent and received messages, and alias support. It can also be started from the command line to send bulk messages to recipients from a text file. It supports sending of large messages by splitting them in multiple files and joining them back together. Senders can be blocked to avoid abuse and prevent spam.
