I found this great site which can enable you to log all the visitors of your blog or website. The site is www.statcounter.com. You can create a new account and a new project. Simply copy the code provided and put it somewhere convenient in the blog template. See where I've put it, down below.
By the way: The blog www.bethanyhigh.com is UNUSABLE!! It should be the next site to be put in the 'Unusable' article in my favourite computer magazine, Digit!!
