Enable threaded comments in WordPress 2.8

How to enable threaded comments in WordPress 2.7 or 2.8? For those using latest WordPress theme won’t be a big problem as the theme should be able to support the features of WordPress version 2.7 and above like threaded comments. All you need to set it at Discussion on WordPress Settings. However, I started to blog since WordPress 1.x and the theme that I am using does not support it. Therefore, I need to modify it to enable it. Planned to do so since last year but only got the chance to make it right now. Yeah… I really love the threaded comments function. It makes the discussion better.


Is your WordPress theme support threaded comments? If no, are you going to modify it to enable it?
