How can I go about doing this?

[HMan]

I've just updated my Busa journal about my sport-touring add-ons along with a small product update.

Now, here is my question. I've had several people email me and ask if there is a way for them to be informed whenever there is an update to the site.

I had to tell them that I'd get back with them. Is there an easy way to do this? Should I just give them an email address to mail me and then send out an email to all that I've recieved from whenever I update?

I honestly don't know the best way. Know of one? Any good programs or free services?
