Okay, so after I made the adjustment to comments, it took me a few tries to get one posted.
When you click on Comments at the respective blog entry, you then need to select a profile under Comment as: (I recommend Name/URL unless you have another profile to use). Type in your name (you may leave URL space blank). Write your comment and select Post Comment button. At this time, you will be asked for a word verification. Type the word and your comment should be posted!
Email me at firstname.lastname@example.org if you have questions.
UPDATE: A good friend has pointed out that if you write your comment and select Preview (instead of Post Comment), the word verification will appear and you can then select Post Comment. This approach may eliminate the error message that occasionally appears. Thanks Parker!
