ProZ.com is based in
Syracuse, New York, United States, and it has offices in
La Plata,
Argentina and
Kharkiv,
Ukraine. The site features a virtual community of translators and offers a wide range of resources. Registered users are able to broadcast their professional identity as
translators on the internet and receive job offers in the mail with the appropriate language combinations. Registration is required for most services. It also provides discussion
forums and online glossaries. Although much of the website requires paid membership in order to be used, and the website receives income from paid advertising, the site has been developed with the help of unpaid volunteers. One remarkable feature is its terminology questions, asked and answered by users; more than 2 million term translation questions have been answered via the site. The website features
reputation systems: WWA for translators and the BlueBoard for outsourcers. Inc. Magazine rates the service as "a helpful resource for small translation projects" but because only paid members could see the going rates, "non-members may have trouble figuring out how much to offer.". (That rate information has since been made public.) A Guardian blog article published in April 2012 referred to ProZ.com as "the world's largest translator organisation". On September 30, 2009, the site organized a
virtual conference that attracted a large number of attendees. Annual virtual translation conferences have been held since then, and are open to anyone with a registered profile on the site. == Cooperation with non-profits ==
