You must be registered on Narrative to perform activities, beyond reading consumption.
Registered members who are Conduct Negative are basically given Read only status - they cannot suggest, bid on or appeal Niches, nor can they post content or comments until they become Conduct Neutral. Reputation Conduct Status is found in Your Profile.
Other activities in the platform require at least a Medium Reputation. This is to allow a registered member to get to know the system and begin to participate before acting on certain HQ activities. You must be Medium Reputation (Reputation Score of at least 50) in order to Suggest a New Niche, Create Appeals, and bid on a Niche.
New or lower reputation members can still create content, comment, and approve Niches (unless they are Conduct Negative).
