How can I see other users' entries concerning their likelihood of working again with a particular client?

"Blue Board" is one of the options under the "Jobs & directories" tab in the main menu. The Blue Board is also accessible by typing this URL directly: http://www.proz.com/blueboard

Once you are at the Blue Board, you can search outsourcers by name and location and even save your search parameters for future reference.

Members are also given the option to sort search results alphabetically or by LWA average.
