I am looking to plan a long trip (2-3 months) along with a friend parttime, in Europe, which is a long way from home (Australia), It will include House Sitting, friends, accommodation, flights, and car rental.
I was wondering if there is any “prior art” in the public domain.
TiddlyWiki Would be ideal for organising a long trip and can be placed online, behind a password, and a local copy retained.
