Do Follow Blog/Article Commenting

Need you to: 1) find 20 news sites which allow do-follow comments. These must be of a certain ranking. 2) create 2 seperate accounts at each of these sites 3) For each account, write a two to three sentence random comment on the topic of an article on each site (without any link). So for 2 sites this is 40 random comments. You MUST write an intelligent comment according to the topic of the article or the other comments thereof. We'll go back and check the article for your posting so please don't cheat this. 4) after you submit the work, be patient as we will test results by posting our own comments (WITH link). Once we've ascertained that the site has allowed our comment, we'll release the escrow.
