I could not find a way for it. If there is none. I request and authorize any of the admins to do it for me please.
By the way, I see you told everyone you would "quit HN" if you didn't get a satisfactory response to this comment: http://news.ycombinator.com/item?id=2088044
There are people here who down-vote simply because they don't like your face. Don't take it to heart. Just keep contributing useful commentary or stories and shrug it off.
So I want to quit. The community by and large is good, so I will be a lurker still. But I shall not be down voted.
PS: Would hate to bother PG with this. Have a lot of respect for him. So request any other admins to just remove my account. After deleting all my posts.
Are you also going to stamp your foot and pout too?
How silly to quit something you clearly enjoy and see value in for something as mind-numbingly trivial as karma--
You simply cannot contribute to any community without the maturity to handle the diversity of other people's opinions and views. Some people here will down vote you for something as simple as beginning a sentence with 'but' or using 'a lot' for anything other than an auction.
Vote up, vote down, the sun" will shine tomorrow.
Relax, why do you care about karma so much? Make your comments, and forget about them. If you get downvoted, you might want to think about why, but acting on it (and throwing a tantrum about it, which this is, basically) is pointless.
Just comment when you feel like it, try to add something to the discussion when you do, and forget about the rest...
To answer your question directly, there is no direct support for deleting accounts. PG might be able or willing to delete it if you email him and ask nicely.
However, it feels like you are angry and you also want to withdraw the content you've submitted as well. Why does that matter? To be honest, your comments are going to fade into history even if they continue to exist. Deleting them aren't going to change anything. Same thing with your account — even open, with no new comments (if you stop using it), it'll fade into essential non-existence as well.
