Double post is it's something big or it's been a while since your last post before the new insight.
editing if it's just minor changes like grammar things, some wording, or adding one a last thought or two about the thought already in the post that doesn't really add anything extra to what you're saying. like... a thought you meant to include. but i mean if it's been more than like five minutes and then you realized you psyducked up well too bad i'm sure someone already saw it anyways. you might as well double post if you want to try and correct yourself.
