This software program has a simple streamlined approach for sending and scheduling informational messages and reminders to participating users or groups. The user interface remains intuitive and uncluttered and is quickly mastered by all users. Fast dissemination of information aids to the success of the business and provides productivity gains. This program does not attempt to replace email systems, but rather to provide a means of providing on-the-spot pop-up information to all participating personnel. Any LanPopUp user can be set to work in one of two different modes of operation, Client or Admin. The Client mode of operation can only receive messages, while the Admin mode of operation can send and receive messages. The mode of operation can easily be changed at any time and reinstalling the software is not necessary. Messages can be sent to selected member groups or individual users. The capability exists to setup 32 system wide groups and users can be assigned to one or more groups. The program may be evaluated for a trail period of 30 days at no cost.
