*Edit*
If you're having problems with the follower gadget on the right, please try using the 'follow' at the top left of the blog. You'll need to have a Google account (don't worry...you're not signing up for anything that will bombard you with junk emails or anything), and be signed in to it to be able to see the word 'Follow' at the top left of the blog (next to the Search box). I've been having some problems becoming a follower at some blogs for the last week, but I am able to do it this way when the follower gadget doesn't work. Hope that helps!
