> I sent an email to a specific conservation project, asking if they happen to need any software help at the moment and they did. We got chatting, agreed on some goals and I got working. I signed their volunteer agreement form which sets out some conditions (nothing unsurprising). That's it really.

For what it's worth I am not even based in NZ; I'm in the UK. Happy to chat in more detail if you want to know more (my email is in my profile)
