RE:MONOMOY - rubber hits the road...
If you plan on taking the South Island trip, that means you're out for the times posted on the shuttle sign up. You can update your information without the need for intervention on our part.
The shuttle database is there to help people get organized and not have to chase multiple threads to determine who plans to go at what time. But it's just a convenience thing as of now. Arrangements need to be made by the groups interested in going.
