How to delete comments?

[funperson969]

Newbie here. I made a booboo with ages in a story, which (not surprisingly) generated a lot of comments. After the corrected story finally appeared, those (now invalid) comments make the commenters look silly. How can I delete those comments?

Never mind, found it. Like I said... newbie. Sorry for taking up the bandwidth - feel free to delete this thread. Or should I start a new thread: how to delete threads?
