Important: Make sure that setting.set file is in /plugins/Plugin_Login/ folder and 0.3v has different option so should change setting.set also which i included in zip file

New (v0.2)

Open the setting.set and you will see

dbname MineUser
tbname users
user root
pass 1234
##
txtmode 1

New (v0.3)

allowchat 1

something like this.

dbname - Database name that will be used in MySql
tbname - Table name that will be used in MySql
user - User id for SQL server
pass - Password for SQL server
1. (just divider)
txtmode - [0 = use SQL mod] , [1 = use .txt file mod]
allowchat - [0 = do not allow player to chat before login] , [1 = allow player to chat before login] --> new v0.3

Then, Plugin will automatically create database with your dbname,tbname

please be aware that space between name and value is single tab key. space bar may occur problem.

Bugs:

message spamming to jumped player who didn't login.

I'm using tab (\t) key as tokenizer so make sure that use tab key when you have to change the txt file.
