With the latest Crew update, one of my requests got implemented to be able to format Crew and Ally chat with placeholders.

• Ally chat now shows Crew name instead of “Ally”.
• Ally chat now shows leaders, they are shown as italic.
• Ally chat now shows Crew tag colors (New!)
• Crew chat shows leaders in Bold.
• Captains that are also leaders can now set the Color and case of their crew tag with the new command /crew modtag &cTag
  This allows setting multiuple colors for your crew name, no limit, no cost, you just have to be both a Captain and a leader, this color change will show in ally chat to make you stand out, its nice to make your crews colors be represented in chat!
  Use /info colors for a list of all colors in game. you cannot change your crew tag words, you can change the case of the words though, so Cove could be CoVe if you wanted. An example /crew modtag &cCo&6ve
