Hello there I have built a blog with codeigniter and I'm trying to make a button so user can get my RSS feed, I'm actually totally confused here that I don't even know how to ask the question...(I don't really use google reader or something like that so I'm not so familiar with the terminology...)is the way to go a technology like SimplePie?Can you give me a proper tutorial that will solve my problem?Thanks in advance!
