Your WP install by default has an RSS feed. Do you mean aggregate feeds?
I am not sure. Where would I find that feed url?
With permalinks enabled, it’s usually http://example.com/feed
I have permalinks turned on but i dont know how to turn it into an rss feed
See one post above yours. The RSS feed is already turned on for your blog.
oh, so the feed url would just be the name url of the site with /feed added to it?
Yes.
You can find a full list here for the different types of feeds if you want to read up on them.
Hope this helps,
