So someone wants me to edit their PLR articles. They are giving me $2 for each article. Each article is about 2-3 paragraphs long. There are a total of 95 articles.

What are these? And what exactly am I editing?

I love to write but I have never heard of these.

I have a stack of duplicate content PLR's (300) and some of them are original but most are not! Is there any software freeware or otherwise that can check several hundred articles against the content online to sift out the original stuff quickly without labouring for hours by googling one article at a time? Thanks in advance!
