>1. When I repley to a message in the UT how do I get the message I am replying to into the new message? (hope that makes sense)

This happens automatically for me. Which makes me think that is something defined in your profile.

>When entering code into the new message how do I get the colour coded coding (white backgroud, blue command words etc)?

Enclose the block of code with the following tags

< PRE >
if a > b
messagebox( "..." )
endif

< /PRE >

You need to omit the spaces between "PRE" and the angular brackets for the UT to actually pick them up.
