I suggest to change the max. length of the username when creating an account on the site, from 20, to 16 because the max. length to login on the game is 16, witch make impossible to login if you create an account with 17, 18, 19, or 20 characters!
I suggest to add some way to change the name, or the email, or delete the account. The only account changes implementation that exists is change password...
I hope you can agree with me on the first part at least and maybe add the name change possibility or delete it so that you can use that email apropriatly.
