I found this in the documentation: Feeds. This appears to discuss what I need, but I don’t know how to use it.
I would like to add a list of the titles from my category Featured and link to them in my Tiny sidebar. Please note that I cannot code myself out of paper bag but I can deal with some HTML and CSS. I was able to put together the sidebar as it appears so far.
Any assistance with this would be appreciated
