I am going to burned for asking this, but I haven't found a good answer. I have been building my backlinks and have found several PR 6,7,8 sites. Would it do any good to post several times to those high PR sites or would just one work. Stupid question, I know. But, I didn't know if it was the number of links from different high PR sites or if it could be just several links from the same. Thanks for your help.
