Bukkit

Requesting the ability to display a suffix. A suffix is useful as a subtle way to distinguish mice from men. If combined with this feature we could have the following scenario.

Group A (Primary)
No Prefix
No Suffix

Group B (Sub-group)
Prefix: "Lvl.1"
No Suffix

Group C (Sub-group)
No Prefix
Suffix: "[VIP]"

Displays the following in chat: "Lvl.1 <Player> [VIP]: Hello world"

If the suffix is simply a code for bold text (&l) you could strategically place the suffix before the player name or message to distinguish members of that group.
