Just got a lovely note from a professor telling me that I MUST register with this site. Turnitin's Originality Checking ensures originality, as well as use of proper citation.

Lovely.

I have lurked here for awhile and I am not about to ask the dreaded question of who is the best and trustworthy. I would like to know which companies are not being used by Turnitin.

I was recently badly injured with my back (4 discs herniated) and missed a total of 4 weeks of classes. I have been given special permission by professors to make up assignments all the way up to Christmas Eve. There is no possible way for me to do the current week and next week's assignments before break and make up 4 weeks as well. I got burned back in early October late September and sure enough a paper I got was right on turnitin.com.

Since it is frowned upon to appeal for a particular site to go to...can we do the reverse and save me precious time by telling me which one's to avoid at all costs?

Thanks so much.
