ProZ.com

Founded in 1999, ProZ.com is home to the world's largest community of freelance translators. Companies that require translations can use the site's directory to find translators or translation companies at no charge. In addition, translators working on jobs have a structured means (called "KudoZ") of obtaining assistance from colleagues on challenging terms. Many other services are provided for translators, including discussion forums, in-person and virtual meetings, the "Blue Board" database of translation outsourcers with reviews, and more. ProZ.com is based in Syracuse, NY, USA, and has additional offices in La Plata, Argentina and Kharkov, Ukraine.
