Installing Elance Tracker on 64bit GNU/Linux
From Organic Design wiki
Tracker
To work on hourly-rate based jobs in Elance you need to install their Tracker tool so that your hours can be logged and reviewed for release of your weekly payments. Unfortunately the Tracker is built using Adobe Air which is no longer supported for GNU/Linux, but it only requires version 2.6 of Adobe Air which was the last version available for Linux and can still be downloaded from the archive, or directly from here.
