(Found this now I have text-to-speech working on tmy mail!)

The simplest way I found to achieve this is via a Module.It can be as 
simple or complex as you wish but needs methods to add messages, status 
codes etc. Then evryone up and down the call chain can see or use the 
messages as tehy will.

For example to raise a message MMsgChain.Add("some text")
