Dear all Many thanks for all the replies regarding the addendum. It has certainly given me food for thought, and plenty of ideas. I will try and reply to some individuals off list, but please excuse me if this takes some time. Having to write my addendum clashes with my house move, rehearsing a play, as well as a very busy summer here at work. But I will try to reply by the end of the week. Once again, many thanks to all those who went out of their way to help me. I have advised some of my collegues who are starting to charter to also sign up onto this very wonderful list. :-) All the best Aaron
