require 'mail_form'

class ContactForm < MailForm::Base
  attribute :name, :validate => true
  attribute :email, :validate => /\A([\w.%+-]+)@([\w.-]+\.)+([\w]{2,})\z/i
  attribute :message
  attribute :nickname, :captcha => true

  def headers
    {
      :subject => "My Contact Form",
      :to => "[email protected]",
