Group Net Send is a simple instant messaging program so that all types of messages can be sent, via the Windows command line (or the MSDOS setting) among all users of a network.
In Group Net Send you just specify the names of each one of the destinations you want to send your message to, although if you prefer you can send generic messages to everyone. The message is in TXT format.
Once the messages are sent, Group Net Send verifies that each one has arrived correctly. Group Net Send is so simple it doesn`t even need installing.
