Multi NET-SEND
With Multi NET-SEND you can send a simple text message to one or more users/pcs connected to a NT LAN, using the Messenger Service. It has a simple but very intuitive interface.
Put the destination pc(s)/user(s) address in the top text (using ‘;’ as separator).
Write your message in the large textbox and press enter to send it.
You can choose to autosave destination users and to close the program when the message is sent.
