RssFwd also has a 'subscribe by email' function to add to your blogs. You can add this to your sidebar or to the bottom of each post. The latter is probably the most useful location, as it is more likely to be noticed by people who are just reading one post, rather than browsing your whole page.
Post subscribe button:
Clicking on the button takes you to a new page where the feed has been auto-discovered and entered for you. All you need to do is add your email address. You are then returned to the page you subscribed to.
It is a quick easy way to add emails subscriptions to your blog. The only reason I decided against using it is because of the statistical tools provided by the service I already use - Feedburner. I will write an article about the Feedburner tools later.
