Quite often I wish to print a topic for later use, when it has long sunk into the bottomless pool of the past.

The only way I know of doing this is to:

a) Select File>Page setup and choose A4 landscape
b) Start with First, print, choose Next, print, ...

with repetition of the original message and post message instructions in each step b).

Have I missed something?

Otherwise I would suggest a Print Topic option, preferably in A4 portrait, and most importantly without repetition.
