Not really. I think tha worst paying job on DigitalPoint will beat the average job payment on Microworkers, therefore I always take my jobs from here
I have considered it but find many of the jobs are junk. Some re-direct you to websites and countries, that most would drather not go to in the first place. If careful you can make some good pocket change.
Microworkers wont really do you any good try elance.com or guru.com. I managed to make quite a lot from there. Best wishes, Riopal
