I would renew it in a second (in fact, I just did!) because last year, when I upgraded to Platinum for the first time, it paid off almost immediately... Thank you!
My workload has climbed steadily since I became a member... Another great advantage is the Blue Board... My latest (very big) job came through ProZ.com, so I would say: "Go for it!"
I was able to become a full-time freelance translator with clients met through ProZ.com. It was the start to my new life and I haven't looked back since!
