Hey guys! I'm running a small server for my friends and we would like a plugin which you can easily change prefixes with. I know that ColorMe exists but I would like something far more simple, plus that ColorMe made my server crash. Thank you for answers, either existing plugins or if someone could make one!
You could try SimpleSuffix. Although it has a misleading title, it can set prefixes as well. http://dev.bukkit.org/server-mods/simple-suffix/
GroupManager works well, nice simple command interface, allows prefixes & suffixes for entire permission groups too
