From the community profile: "The Cortex is a fandom newletter that features the news and events the fandom is interested in, as well as links to fanfic, art and discussion. We will try our best to feature new authors and artists as often as possible.
The best source of Firefly or Serenity news is by the Browncoats themselves, so tips and recs are always encouraged. Feel free to send us an email at firstname.lastname@example.org, or leave a comment to any of the daily posts."
New Issues of The Cortex are posted once every day, including weekends.
