In-Short: Those type of questions are likely the reason for incompatibility.
My assumption
To possibly lessen your confusion:
It would require a server side plugin to change the name visually, automatically(since doing it manually would be too time consuming). Likely this would have to be tied in with the KreatiousLock(?) plugin to change the [private] signs accordingly. I'm not sure about ranks and such since some are custom done via the
Store page. Also I recall Zerg mentioning once or twice that the reason it takes donors a long time to get their ranks ingame is because they need to be on the same time he is. So he can assign the Prefix to their name... As with the Rsd rank it's automatically done once the defaults reach requirements.
Mojang's post for name changes (for those who don't know...)
https://mojang.com/2015/01/announcing-m ... e-changes/A few of the questions they have give minimal insight on the matter.
If I ban a player “Foo” and he changes name to “Bar”, will he stay banned?
Yes. Same for whitelisted players and oped players. They also keep their inventory, pets, statistics and everything they own on a server.
How will this work with mods? What about my custom stuff on this one modded server?
Ask your mod maker/server owner. Mods should be able to support this system easily and most already do, but we aren’t responsible for mods or servers!With this we can say that not all hope is loss for name changes. It IS possible for mods/plugins to be compatible. but for now. Keep your name as is for the time being.
