IPM function no longer used

The InfoPrint Manager team is looking at functions from IPM which may no longer be used by customers. Typically, as functions are used by customers we track issues and support provided.
Several of the clients we have NEVER heard about are:
- InfoPrint Submit Express
- InfoPrint Select and Command Line Clients on Mac OS
- InfoPrint Select on Linux

We use a lot of resources to maintain these clients, with very little to no apparent usage by customers.

Please reply to this thread if you use any of the above listed functions.
