Yesterday I've added AskUbuntu RSS Feed to TechyTalk.info sidebar to display feed of Ubuntu related questions with links to answers all provided by the Ubuntu community. This is really useful service. I've used WordPress RSS widget to display this RSS feed. The problem I've ran into was that WordPress RSS widget feed was refreshing only once in every 12 hours and for my purpose this is not often enough. In this article I will show you how to change WordPress RSS widget refresh interval.
