Could &m be added to /help colors? I think it should be on there, it would make a lot of sense because other formatting codes such as &n are listed. Kinda like this: ---- Help: colors -- Page 1 of 1 ---- &0 Black &1 Dark Blue &2 Dark Green &3 Aqua &4 Dark Red &5 Purple &6 Orange &7 Light Grey &8 Dark Grey &9 Blue &a Light Green &b Light Blue &c Light Red &d Pink &e Yellow &f White &l Bold &n Underline &o Italics &m Strikethrough Shouldn't be too hard to add...
It can be used in nicknames, most people don't even know about it. It also can be used as formatting in chat if you have the patron rank.
Most people don't know about it because nobody really talks about it. Again, it doesn't have much of a use. -1 to the suggestion.
It has as much use as other formats, I don't see why it shouldn't be included. It would make sense to leave it out if it didn't work in chat and nicknames, but that isn't the case.
