There is something new available for those who make comments on this blog, or if you’ve considered it but wondered about getting an answer.
When you post a comment, there is now a checkbox near the submit button that if you choose to check it, means you will be notified by email if anyone else posts a reply (such as me answering one of your questions!) to that comment. It doesn’t mean you will suddenly be emailed every time there is a comment anywhere on this site, only for the specific post you’ve commented on. (Given the average post has at most 2-3 replies, this doesn’t mean your inbox will suddenly get inundated!
You don’t have to use it, but it is a tool that is available to you if desired.
