There seems to be some confusion about commenting on the blog. We've made it pretty easy for you, so here are some simple steps...
After you write your awesome comment... which by the way should be on topic and good, choose your profile. If you don't have any of the logins available, just select anonymous from the bottom of the list.
Then click PREVIEW
Preview - make sure it's what you want to say, complete the word verification if you're not logged in - and post the comment.
And there you go!
