I've long wanted a plugin that moderators and admins can use to keep notes on players, to assist in coordination. No need to delete notes. Keeping it simple: /rec player note: adds a note /rec player: shows notes on player. One possible use case would be to keep track of warnings to that player, or deals made. For instance sometimes I will unban a player on the vouching of their friend, so: /rec player1 unbanned player1 on word of player2. ban both if player1 turns out to be a jerk. /rec player1 griefed building at ticket #933. Not serious, but issued a warning. Or, just (possibly catty!) warnings to your fellow mods: /rec player1 Player does not speak English as a native language, be patient, is a nice guy. /rec player1 can't tell if is trolling, or just stupid.
