Subreddit Rules
  1. Do not ask us to diagnose your symptoms: We can't do that
  2. one can do that other than a qualified specialist. CF affects everyone differently. Please, book an appointment with a doctor if you believe you may be experiencing common symptoms of Cystic Fibrosis.
  3. Post promotional material to the designated thread: Please, post any promotional material to the right thread. There is a new self-promotion submission made each Monday. This content includes blogs, vlogs, charity or assistance, requests to help with research, art, and anything else considered promotional in nature.
  4. This was done to prevent the dilution of discussion amongst the users here, as there was a time where the majority of content posted to the subreddit was blogspam and drove users away. This is how we compromised.
  5. Do not promote alternative therapy: Don't promote alternative therapy/medicine that encourages people to replace their current treatment, or that could be dangerous. These posts will be removed and you will be banned. Discussion of alternative treatment as a supplement is fine.
  6. Be civil: We shouldn't even need to make this a rule, really. We're not the politeness police but we reserve the right to mete out bans for egregious violations of this (as determined by mods).
  7. Trading medication will not be tolerated.: Trading medication is illegal in many countries. not only that, but it carries many risks to the health of our members. Please refrain from posting anything that may enable the trade, sale, or gifting of medication.
