Thought this was suggested a while ago but I guess not.
Basically this suggestion is to allow a separate place from our player name to allow for a short tag to represent our guild. This could be set at the guild level or set by players, this would essentially let players in a guild feel more like a part of it while not limiting how long their username is while also not requiring the same gems that a knight name change requires.

Awesome suggestion, Idk why this isn't a thing yet
