Although there are many plugins available for pasting code into posts, this is the first I’m aware of for pasting code into comments. It’s very simple: To have code look right, all your commenters have to do is surround it in
backticks, just like you can do in the WordPress.org support forums.
For demos, check out the KB Backtick Comments demo at my site.
One important note. This plugin will always work in comments, but it will not work in posts unless you first disable the visual editor.
If you post your support questions as comments below, I probably won’t see them. If the notes in the plugin file don’t answer your questions, then post your support questions on a post in the KB Backtick Comments category at my site.
