> To address this and many other issues and requests, I'm currently working on extending the chat permission systems in order to make three things possible that currently aren't (with the single exception of suspensions):
Subtractive permission adjustments. As I said here, the current permission system only allows you to give users additional permissions, never remove permissions from the default set.
Temporary permission adjustments. This will, for example make it possible to give users time-limited permission to chat despite low reputation, or ban a user from a single room temporarily.
