Thanks to a reader comment, I’ve just noticed that all of my articles on EnglishClub.com have slightly different addresses. I’m going through one by one trying to mend the links, and if you find any please let me know and I’ll fix those ones asap.
In the meantime you’ll just get an error message if you click on a broken link. However, you can easily end up at the right place by googling the name of the article (maybe with my name or the name of the site) or the original address.
