A really useful internet aid for identifying these meassages hidden in the initial letters of superfluous words is chris fa johnson's wordfinder:

For example, if you search for 'words matching' and type in the intial letters for the last 4 clues as follows:
[kaciasot][opctsb][fasdpc][fcbetin]
you will get a list of 30 possible words, including CODE. It didn't take long to establish the entire message using this method, thereby providing invaluable help for solving the clues and entering their answers.
