Currently at my personal blog, lerner.net, I am using Subscribe2 HTML for blog posts and a separate plugin Subscribe to Comments Reloaded for comment subscriptions.
I am wanting to switch from Subscribe2 HTML to WPMU DEV's Subscribe by Email because of some issues with Subscribe2 HTML (even though Subscribe2 HTML has a preview of the latest post by email and Subscribe Email does not).
Anyway, my question is, what should I do about Subscribe to Comments Reloaded? Is it recommended to continue to use it? Or does Subscribe by Email include subscribing to comments? Or is there an alternative plugin that is recommended for the comments? Perhaps something by WPMU DEV?
