If you've recently joined the Less Wrong community, please leave a comment here and introduce yourself. We'd love to know who you are, what you're doing, what you value, how you came to identify as a rationalist or how you found us. You can skip right to that if you like; the rest of this post consists of a few things you might find helpful. More can be found at the FAQ.

A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.

Welcome to Less Wrong, and we look forward to hearing from you throughout the site.
When discussing such questions, we need to be careful to distinguish the following:
I am inclined to give different answers to these questions. Similarly for Parfit's repugnant conclusion; the exact phrasing of the question could lead to different answers.
Another issue is background populations, which turn out to matter enormously for average utilitarianism. Suppose the world already contains a very large number of people wth average utility 10 (off in distant galaxies say) and call this population C. Then the combination of B+C has lower average utility than A+C, and gets a clear negative answer on all the questions, so matching your intuition.
I suspect that this is the situation we're actually in: a large, maybe infinite, population elsewhere that we can't do anything about, and whose average utility is unknown. In that case, it is unclear whether average utilitarianism tells us to increase or decrease the Earth's population, and we can't make a judgement one way or another.
