RumpelstiltskinRSS is a web based RSS reader for your Gengo Jobs RSS. After some one-time steps, you can use any browser on any device to alert you for new jobs. As a bonus, RumpelstiltskinRSS does some filtering for you so you will only be alerted if the size and level of the job meet your preferences, taking the time of day into account.
I optimized RumpelstiltskinRSS for my own needs, but tried to make it so that it can be used by all translators. You can find RumpelstiltskinRSS at http://rumpelstiltskin.appje.nl/rss/. For a description how to use it, follow the Introduction link.
Note that you can set the refresh interval to either 31 or 62 seconds. Use 31 for optimal chances to grab a job, without breaching Gengo's demand to access your Jobs RSS at most twice per minute. Or use 62 to test if RumpelstiltskinRSS suits you, while still running your current RSS reader (set to check at most once per minute) on another device.
