FAQ for Net Send Lite v3.02   

How do I send a message to all users in the Domain/Workgroup?

Click the Add button and add the name of your workgroup or domain with a * after it. For example, if your domain name is mydomain, then you would add mydomain* into the Send To value of your add/edit users.

Only registered users of Net Send Lite can send messages to the entire domain or workgroup.
