Install: Standard. Drop jar in your plugins folder and edit config.yml.

Config:

Main:
WaitTime: 900 - time to re-login (in sec)
KickMessage: "You can not enter the server within 15 minutes!" - message, which gets the player when the time has not expired.
UsePermissions: true - use permissions or not, needs Vault

Permissions:

noinstantlogin.add - Allow adding players who can do fast re-login
noinstantlogin.remove - Allow removing players who can do fast re-login
noinstantlogin.list - Allow watch who is on the list to do fast re-login

Commands:

/noinstantlogin add nomaf - now, player can do fast re-login
/noinstantlogin remove nomaf - now, player must wait to re-login
/noinstantlogin list - you can see who can do fast re-login

You can also use /nil instead of /noinstantlogin
