Ask HN: Is it possible to resubmit Show HN?

Is it possible to resubmit a Show HN ? I tried to do a new Show HN (since there was an update), but it seems to get redirected to my old post.

Re-submissions of a link are counted as upvotes of the original post, unless theres a certain amount of time between the posts. I'm not sure if it's ever been publicly stated what that amount of time is.

One common hack is to add some meaningless URL parameters at the end of your link, so http://google.com/ becomes http://google.com/?hn

Please don't abuse this, though!

Ok. Thanks ! I re-submitted mine (since there was a new update) and it went through.

Reposts in general are ok once or twice if a story hasn't had significant attention in the last year or so. But once a story has, we bury reposts as dupes.

If you read the Show HN rules (https://news.ycombinator.com/showhn.html) you'll see that to qualify as a new Show HN there needs to be some major new development, not just a new feature—but that only applies after the "significant attention" test has been passed. If any of that doesn't make sense you're welcome to ask us at hn@ycombinator.com.
