There a plugin(s) that change your username look, but they probably aren't compatible or Andrew would rather not have them. o.o
A nickname would be easier (For me, at the very least) than a custom name tag... Since I can't think of anything that would look good before my name <_<'
There is a command /nick (your nickname) which makes you ign change to the nickname with a ~ in front of it, so like [g] [Mayor] ~mymine . The problem with this is it makes it a pain to tp and pm. Is this what you mean?
Guys, don't necro old topics like this. :| This is very, very old, and something Kuke wouldn't suggest today. xD
I suggested this too xD Everyone said no because it would make your real username (used to pay, message, etc.) difficult to find out. Also, it's part of essentials which is one of the most basic mods
Locked Don't start a discussion in a Old thread such as this, if you think it should be added, then say so in the suggestions forum in then new topic.
