I have a suggestion.
If you require free articles to reprint or use as PLR, modify and use, anything at all, you can use articles from
http://www.phototamasha.com/blogs/
No costs involved, you can pick up anything you like whenever needed and if you want to give credit you can, if not even that's fine.
They are actually originals being published on this site for the first time, and anyone can use it. Simply follow the tweetbird on top of the page to get continuous updates each time a new article is uploaded.
Hope this helps you.
Thank you, regards, n.
