1. You can't edit comments over a certain age (about 2 hours)

2. You can't edit comments after someone has replied to it. (I think?)

Helpful tip:

There is a search box at the bottom of the page: https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...

Generally:

"Please don't comment about the voting on comments. It never does any good, and it makes boring reading."

But there are other guidelines there which might be useful. Good luck!

#2 is wrong, you can edit your comment after someone replied, but it canbe bad netiquette.

I fix silly typos without warnings (very often).

I make a substancial change, I add "Edit:" or something similar. (Not very often. Most of the times I add another question or source.)

(I also add "Edit:" when I fix a very bad typo noticed in one reply.)
