Categories are used to "tag" your blog posts. That way, your readers can quickly find everything you've ever said about the Philadelphia Eagles or NASCAR or Kobe Bryant. You can attach as many categories to a blog post as you'd like!

If you'd rather not tag your posts, of course, you don't have to. Categories are completely optional.

To add a category to your post, just start typing in the "Category" field. Some suggestions for what category you're after may appear as you type; you can use our predefined categories, or create new categories of your own.

RSS stands for "Really Simple Syndication." Instead of having to come back to your favorite blog every day to see whether new content has been posted for you to read, you can subscribe to a site's "RSS feed." Then, using an RSS feed reader, like FeedDemon (for Windows) or NetNewsWire (for Mac), you can find out whenever a blog has been updated, without needing to check it yourself.

Still not sure what that means? Think of a microwave. When you stick dinner in the microwave, you could come back and check the microwave every twenty seconds to see if you're food's done - but that would be ridiculous! Instead, of course, the microwave beeps to let you know when the mac and cheese is warm.

In the same way, an RSS feed reader saves you from having to constantly check your favorite blogs. Rather, your feed reader tells you when there's new content to read -- and all you do is tell it which blogs to keep track of!

Your FOX Sports blog offers an RSS feed with summaries by default, which you can change in your Blog Settings.
