###Rules (hover for info)


Don't be rude or disrespectful to other users.	This could be in the form of hateful mail, hateful comments, and/or flame wars. Anything of this nature will be removed on sight.
Please check that your submission hasn't been posted already.	The search box is a great tool... Use it. Repeat submissions will be removed (unless they add new content).
No spamming.	If your post hasn't appeared yet, you should message us asking for approval. Don't spam your topic/comment due to a lack of response.
Submissions must be Cosmos-related content.	If a submission is simply about Carl Sagan or Neil Tyson but not about Cosmos, more appropriate subs would be r/CarlSagan and r/NeilDTyson. Exceptions include AMAs from people in fields that would be of interest to Cosmos viewers. If you need help finding a suitable subreddit, click here.
Your submission title should be descriptive.	Vague titles (titles where the viewers are trying to figure out what's trying to be said) will result in the post being removed.
No memes.	This is extremely simple. "No memes".
No linking to piracy.	Piracy is anything that is a non-purchased/non official copy of Cosmos. Don't link and/or ask for pirated links to episodes. Streaming links for the original series on major video hosting sites are a grey area
No Crowdfunding links.	Anything related to Crowdfunding (Kickstarter, IndieGogo, etc.) will be removed on sight. Unless there is a really good reason behind a kickstarter, they will be removed accordingly.

###Note on piracy

Please don't link to illegal streaming or download sites on this subreddit, or your post may get removed. Similar to how r/BreakingBad handled things, you won't get in trouble for sharing streaming links in the IRC chat, but please don't post any in the subreddit itself.
