There may be an easier way to do this but this is what I did.
Open the message and in the top right hand corner of the message is box marked 'quote', click on it.
At the top of the message in the 'to' line there is a button marked 'remove', click on it.
On the very left hand side is a section marked 'send to'.
In the box under 'user names' click the mouse there and a flashing cursor should appear.
Write the name of who you want to send it to, eg melaniem or stuss.
Under the box is a button marked 'Add [to]' click on it.
that name should now appear ove the message on th 'to' line
Add any thing you like to the body of the message and click 'submit'
Hope that helps.
