The largest freelance community online has the benefit of also being the most popular. Most of the jobs listed originate from the western side of the world. However, oDesk listings tend to lean towards technology based work that can be accomplished by anyone with an internet connection.
Behind oDesk is an automated time tracking system, so that freelancers can be paid by the number of hours they actually work. This also means that freelancers won’t have to worry about tracking their time and can actually get work done. The system also automatically hands out payment weekly, so the only thing standing between you and your extra cash is, well, you.
