Some time ago, I shown you how to display the total number of comments on your WordPress blog. With a little modification, this recipe can be used to display the total number of trackbacks.

Some blogs have over 100 comments on every new posts, which makes the page extremely large. So lets say you want to shorten those pages by making the comments collapsable, well there is a easy solution for that! jQuery! We are going to integrate jQuery into Wordpress and make the comments collapsible!

Though this isn’t quite the same as displaying your most popular posts in your sidebar, here is some code you can use to display the posts that have received the most comments.  You’ll want to place it in your sidebar where you want the code to be displayed.

WordPress 2.7 is introducing many new features surrounding comments. Of these is AJAX commenting and threaded comments. To take advantage of the later, you must use a function wp_list_comments instead of the old way of looping through the comments array with a foreach.

An often-used feature on WordPress blogs is the ability to style comments made by the post’s author differently from the others – helping replies to stand out. Here, we will edit the default WordPress to add some subtle styling to author comments.

I love it when it comes to styling the comments. I always find it a challenge to do something different. But my favorite part of comment styling is the author highlighting.

What we’re going to do is instruct WordPress to identify specific author emails and assign a unique class name to each.

In the default of most themes, all comments look the same. There have been ways of changing the appearance before using plugins and hacks – and this is more of the same. Hopefully though it’ll give you some extra flexibility.

Fight spam by making your visitor write a comment a bit longer then usual.

Add Gravatars to your WordPress theme. Gravatars are a quick way to add a personal touch to your blog comments by displaying the avatar of the commenter alongside their comment.
