In case you want to check by visiting the forum instead of waiting for emails, there is a link at the top of each webpage, on the right hand side of your EEVblog avatar, called "
Show new replies to your posts.". Then, the small "New" icon near each topic will position the page to the first new reply not yet read by you.
If you click on that text at the righthand side of your avatar (in the banner area of the page), it will open a page with all the places where you have unread replies.
Same for "Show unread posts since last visit.", that's another link to see new posts, except that's for the whole forum and not for just the threads where you wrote.
