Everyone is operating on G3s and has system 8.1. We also have an ISDN line for internet access. We have contacted Microsoft and they do not plan on offering a similar Mac program and the Eudora Planner release keeps getting pushed back. Once again, the answer may be Consultant. Since I don't have any experience using it as a multi-user application, here is what the Chronos Web site says.
Consultant supports multi-user network access.
There are no special program modules required to use Consultant on a network. It works directly with the MacOS and the underlying network protocol to communicate over the network. This eliminates the need for complicated network setup and software configuration. Flattery will get you everywhere. Thanks for the kind words.
