I started this blog 10 years ago and since then I was using a free wordpress.com plan. Recently I have taken a paid plan which includes a custom domain. My blog URL has been changed from ‘https://arnabroychowdhuryblog.wordpress.com‘ to ‘https://arnabroychowdhury.com‘. Also there will be no unwanted advertisements in my blog anymore. I have taken the ‘personal’ plan in wordpress.com. I need to renew the plan in every two years and the custom domain in each year.
