Paul Mison's dashboard

It's longwinded, but if you go to the calendar, and then go back to a previous month in which you took a trip, the dates of that trip will be highlighted. Clicking on that allows you to view that trip page, which allows you to edit trips or see previous trips (both links are in the top right corner).

If you've enabled the "Your carbon" tab, then that also provides a list of months in which you took trips (which isn't quite as useful as a list of trips; I believe the Dopplr staff are aware that people would quite like this), which might save you paging back through the calendar.

I'd also like a more easily accessible list of trips, though.

There's documentation for a Dopplr API on a Wiki, but it's preliminary: "This wiki is where the Dopplr API will be developed and iterated upon in public." However, there is already a small app that uses that to generate KML files.
