Please note that I’ve cancelled that option.
I have over 800 RSS subscribers, but after a few months, only a few of you chose the email option instead, and I couldn’t justify the expense of maintaining it.
So that you never miss a post, I’d recommend that you sign up for the RSS feed.
I would still recommend AWeber.com if you are looking for an email newsletter subscription service. Their customer service was great and they didn’t hassle me for cancelling.
