Disclaimer: Due Google has changed recently its quality standards and began reviewing websites for bad linking practices (they are searching for websites who are part of link
trading schemes and sites with links that are considered “over-optimized”) I am forced to remove any link that I have with onlinephd.org, as this page is under review by Google. This is not a permanent change. In time, they will welcome links to their site. This is just for the time being, while they clean things up a bit.
Many thanks for your understanding.
