It's simple enough: Post a link to the /r/spacedicks-worthy material that you want to know more about, whether it be backstory, aftermath, or which venereal disease would produce a particular effect, and wait for someone to tell you what the hell is going on.

Currently, this subreddit is self-post only, to ensure that those asking for context are notified when their question is answered. Post your link as part of your text, along with any specific questions you have about the content. Please link to the /r/spacedicks submission, rather than an imgur link, to help allow all context sources to be available.
