Question about livejournal?

If I leave someone a comment it gets sent to their email, will they still see the comment if I delete it before they see it in their inbox?

If you post a comment then delete it, they will see the comment (in its entirety) in their inbbox but when they click on it they'll either get an error message or they get told the message has been deleted. I forget which. It doesn't matter how fast you delete it, the message that they have a new comment gets sent instantaneously.
Reply:they will still get it even if you delete it.
