Got a question? Post it here and it'll get answered. (Version 2.0)

Previous thread with MANY answers here

I want to set up a thread where newbies can come get the answers to their questions, no matter how simple they are. I will do my best to answer any and all questions posted here, but wouldn't mind if a couple knowledgeable posters pitched in.

Please try to keep questions focused enough to be answered in a paragraph or two at most.

Before asking a question, please make sure to check the FAQ thread [here] (https://www.reddit.com/r/NexusNewbies/comments/348f6s/lets_compile_an_faq_together/) and other questions posted here first.
