This blog, another one of mine and a few other people that I know run their blogs off this code that I´ve written. It´s not exactly feature rich but it does the job.
One of the things it does do is send out an email to people who´ve "subscribed" to it when I make a post. Only problem is that some of these people don´t check their email as quickly as I post, especially if I post a couple of times in one day. A few of them have asked if I can get it to only send them one email in a day. Sounds reasonable and will be fairly easy so think that´ll be next on my list of things to do.
Ask and you shall receive!
