Thank you for reading this blog. We have received some spam-ish comments on this blog and we changed the setting.
Now everyone can leave comments but if you are not logged into Google (or some other services like WordPress etc.), you are asked to type some letters and it also requires the approval of the admin.
Please select your profile. If you don't have any, you can choose 'Name/URL' or 'Anonymous' (the former is better).
You don't have to add URL.
This is a 'publish' window after a 'preview'.
You are asked to type the letters (/words).
"Your comment will be visible after approval"
Please wait for a while.
Thank you for your cooperation.
