Telligent Community 6.x: change the text of the minimum username length error.

This is the default message for the jQuery validation on the client-side.  It can be customized within the User - Login and Create widget's ui.js file.  Replacing

if(context.inputs.username.length > 0) {
  context.elements.createAccountLink.evolutionValidation('addField',
    context.inputs.username,
    {
      required: true,
      minlength: context.usernameMinLength,
      maxlength: context.usernameMaxLength,
      username: true,
      usernameexists: true,
      messages: {
        username: context.resources.usernameInvalidUserName,
        usernameexists: context.resources.usernameDuplicateUserName,
        required: context.resources.fieldRequired
        }
    },
    context.inputs.username.closest('.field-item').find('.field-item-validation'), null);
}

with

if(context.inputs.username.length > 0) {
  context.elements.createAccountLink.evolutionValidation('addField',
    context.inputs.username,
    {
      required: true,
      minlength: context.usernameMinLength,
      maxlength: context.usernameMaxLength,
      username: true,
      usernameexists: true,
      messages: {
        username: context.resources.usernameInvalidUserName,
        usernameexists: context.resources.usernameDuplicateUserName,
        required: context.resources.fieldRequired,
        minlength: 'MESSAGE'
        }
    },
    context.inputs.username.closest('.field-item').find('.field-item-validation'), null);
}

will show the "MESSAGE" when the minlength rule fails.
