I just had a look at the FAQ and it's supposed to link to another page but the page comes back 404 so I don't know what's up with that. The FAQ is terrible. We do have a wiki that is only slightly less terrible
http://www.theflatearthsociety.org/tiki/tiki-index.phpIf you have some specific questions, just go ahead and ask them in Flat Earth Q&A. You can start a new thread, or if you see another active thread discussing your question already, feel free to jump into the conversation. If you want to start a debate on a topic, post a new thread in Flat Earth Debate, or if there's one already going on that you're interested in go ahead and post.
It's best not to try to cram a bunch of questions into one thread, but people do it all the time. Also, there aren't many flat earthers left so you might have to be patient. You're more likely to have a round earther give you a sarcastic answer. (just because someone posts here doesn't mean they think the earth is flat)
