Adding a Subject Field to comments

Hi there,

To start with; thanks for looking into this.

I’m in the middle of creating an extensive website, featuring photoshop contests/challenges. I’m using single posts for setting the challenge, and the comments system (modified with the threaded paged comments plugin) for the community/responses by contestants.

So far everything is working great, except for one thing that I can’t seem to solve; adding a subject field to a comment, thus being able to feature this at the top of a comment.

Is there any easy way – for, say, a nonce like me – to implement this functionality?
