UHRS is accepting new workers again and it can be quite a good and quick way to earn a bit of money. They have different tasks available, the ones I've been doing have been on behalf of Microsoft I think, and for each web site that pops up you have to classify it based on how 'adult' the site is. Therefore you have to not be easily offended by pornography sites!

UHRS is accessible through Clickworker. Register with Clickworker via the attached link and then go to assessments, you will need to complete and pass the UHRS assessment that shows up - I think the pass rate is 70% but it's a pretty easy test.

UHRS is a little bit like Amazon Turk but with better paid and quicker tasks, and a much more user-friendly layout.
