Many clients take work without paying for it and Guru.com does NOT help at all. I am a professional writer and technical consultant and feel a responsibility to warn others about the site.
I wrote a 42,000 word book for a client, Rebecca Farlene on guru.com. She took my work without paying and the site was less than helpful. Do not waste your time or effort on Guru.com. Besides facilitating theft of intellectual property, they are rude and disgraceful.
The client stole my work and the site does NOT care at all.
