The privileges section in the help center should be updated with recent change in the privilege threshold.
There was a change in privilege thresholds on 3 September 2017. The new change implemented was adding a minimum reputation for posting selfanswered question. According to this change, a user needs a minimum reputation of 15 to self answer their question. All the privilege thresholds are given in detail in this answer.
This change is not reflected in the help center.
So, the privileges section should be updated with this change.
