However, if the commenters have flipped to the top of the page and do not scroll back down to see that their comments did not publish, they will leave your blog not knowing you did not receive their comments.
The solution to this problem is very easy. Instead of having your comments box set up in the format that is called "embedded below post", like this:
You can change it to the setup which is called "full page", like this.
If you want to change your comment settings, go into the dashboard, into "Settings" "Comments" and next to "Comment Form Placement" change it to "Full Page". You will find you will receive many more comments than you are receiving now.
Unless you have a really controversial blog -- which most of us don't -- it's always a good idea to make it as easy as possible for your readers to post comments. "Word verification" and "comment approval" -- unless absolutely necessary -- are not usually a good idea. It's like having a welcome mat at your front door that says, "Thank you for visiting, now please go away..." None of us wants that.
I hope to be able to visit you all, as soon as I am able to post comments.
