If you want people to be able to subscribe to your WordPress blog, there are a few different ways that you can do this. One way is to use a subscription form plugin, such as WpSubscriptionForm. This plugin will allow you to create a form on your blog that users can fill out to subscribe to your blog. Once the form is submitted, the plugin will automatically add the user’s email address to your subscription list.
Another way to allow people to subscribe to your blog is to use a RSS feed reader plugin, such as FeedBurner. This plugin will allow you to create a RSS feed for your blog and then add this feed information to your WordPress blog’s RSS settings. Finally, you can also use a third-party subscription service, such as MailChimp or Aweber, to manage your subscription list.
