Articles with Private Label Rights should always be re-written or put through a spinner before they are submitted to article directories. Because articles with plr are sold to many people those articles are going to be used all over the internet. If you use plr articles online you could end up being penalized by the search engines for having duplicate content.
When you are article marketing you must use original content. I use my plr articles as a guide, and then totally re-write them so I have a article that is truly my own. Personally I hate article spinners, and never use them, it is usually easier just to re-write the article, and then your final product is of much better quality.
With a plr license for a product you can do anything with it. You could turn your plr articles into a ebook, blog posts, or forum threads. The same goes for ebooks with plr - You could turn each chapter of a ebook into a ecourse for your list.
