UHRS is a crowdsourcing platform with a variety of tasks geared mainly towards search engine refining and optimization. As far as I know, it is related to Microsoft and Bing. UHRS can be accessed through Clickworker, Appen, iSoftStone (to some degree) and possibly other sites. I personally have only used it through Clickworker, so I don't have information on how to sign up through any other site. They only want you to work through one platform, so if you have an account with one platform it may be difficult or impossible to get one through another. In the past, it has been open to international workers as well as those in the US. They sometimes close qualifications, depending on the current workflow. More information later, hopefully.
