Last time I really needed to get a question answered I constantly emailed people.
Did they give you a constructive answer?
Yes, it was a good, concrete answer.
It's okay to look for answers from others, but bothering people until they help you is the wrong approach to getting help. When someone doesn't respond after a couple of emails, then move on to someone else.
That doesn't make sense, I need to get my answer.
Whenever you need an answer you ask once, and then you wait until you've received it. Maybe a few days later you ask again if they are taking too long, but pestering people just makes them dislike you even if it gets you the answer quicker once.
