Syntax: ignore (<player>) ignore clear channels. It will also block output from tells/reply, emotes, pmotes, says/sayto, think, and whisper. Your messages will still be visible to the ignored player on public channels unless the player ignores you too. This is a discrete option. The ignored party will not be able to find out if you have ignored them. They can still send you tells which you won't receive and use socials on you which you also won't see. You will still be able to see some of their output on channel histories depending on which channel history you are looking at. Typing ignore without an argument will list any players you are ignoring. To remove a player from your ignore list, type 'ignore <player name>' once more. It is impossible to ignore an Immortal.
