RE: include previous message to forwarded message
Hi Ingar,
you have two options:
1. Create a new "Forward messages" screen, which will include the forwarded messages in the message history of the request. This is a bit of a time consuming job, and you need Expander Services to be able to create screens, but would enable you to do exactly what you ask for.
2. The second alternative is to just "Add comment" and paste previously added messages in the message box by using the "Insert" function:

This is a bit more manual, but here atleast you would be able to have the messages you forward stored in your request so that you know which messages have been forwarded.
Hope this was of some help.
