Tim,
I did exactly what you're planning to do five years ago and had the time of my life. Do it, enjoy it and don't worry about a single thing. You'll enjoy every single bit of it. Any other support you need, please shout up..
Azreal: the problem with advising on something you've only 'heard' is that it's misguiding. The Maori people are among the best in the world in terms of brotherhood, unparallelled support (backup) and genuine friendship, which is a very rare find these days.
And Louise: Since when did I fall off the list?
