For anyone that would like to make it easier for readers to comment on your blog. This is how you get rid of word verification stuff on Blogger.
You need to go to the old Blogger interface - on your dashboard look up to top right, click the little wheel and it will give you the old interface as an option. Click that. You will see a big blue button - don't click that - click the one 3 along to the right - settings.
Then click the comments tab - scroll down to the question "Show word verification for comments?" and click no.
To go back to the new interface just click the blue " try the updated blogger interface" at the top next to your email address.
PS I hope this is helpful. Feel free to copy and use the picture.
