This is an old topic that has been covered by many other blogs and magazines–to the extreme, but it needs updating. I’m talking about how to highlight comments posted by the author of the article. The tutorials out there only work for one user ID for the whole site. That is a big mistake, as it didn’t allow for scalability — it only works when you are blogging on your own (and with only one account). We have given it an overhaul, and updated the code.
