To all my followers, just a little tip for your blogs. This is a trick to remove the captcha in your comments.
While it can be helpful for stopping that random spammer, it does make a difference to your loyal followers who love to comment.
Here's what to do:
1) On your blog's main page, head to "Design". This can be found also while editing a post and other similar tasks.
2) Head to the "Settings" tab then "Comments" as a sub-tab
3) Here you will scroll down to see something like the image above:
"Show word verification for comments"
4) Simply choose "No", and save. From there you will have a Captcha-free Blog!
Hope this HOW TO helps you out with your own blog. Feel free to comment below.
