Reply to Re: Levelup question
If you don't have an account, just leave the password field blank.
And by extension, the difference between the experience you needed for the last level and the one you need for this one is 100(2n+1), where n is your current level.
So level 1 needs 100, level 2 needs 100+300, level 3 needs 100+300+500, etc...
So level 1 needs 100, level 2 needs 100+300, level 3 needs 100+300+500, etc...
