Hi Sharon, its over to the right. when you turn on your dashboard you will see the name of your blog. in my case I have two of them so for each blog there is a name of it and then to the right there is an orange box with a pencil on it. ( that lets you make a new post) to the right of that is an html button that looks like a piece of paper. next to that also to the right is a arrow for a drop down menu ( its almost stuck to the paper button) click this, it gives you things like over view posts stats... that has a scroll down button, scroll it all the way to the bottom to settings.
then the page is going to change
over on the left there will be a list of things you can do to your blog
one of them is template, scroll down. settings is right underneath that. so when you click it, a second drop down menu opens up next to it and one of them is posts and comments.
that you will have to scroll down the page a little to see the word verification button to unclick.
