Subject: sending email body text based on form content

As a noob to Rails and web development in general, I think I still need 
a broader understanding of how Views, Controllers, and Models pass 
information and variables to each other.

I'm creating a site that allows for email campaigns.  I have a 
'create_email_controller':

class Admin::CreateEmailController < Admin::BaseController
	layout 'admin'
  def index
    write
    render :action => 'write'
  end

  def write
    @email = Email.new
  end

  def email_list
 	 email = Email.find(:all)
 	 email.each { |address| MailList::deliver_send_email(address) }
 	 redirect_to (:action => @section)
  end

end

where I want the user to type a message body into a textarea field:

<%= error_messages_for 'email' %>

<!--[form:email]-->
<p><label for="email_message">Message</label><br/>
<%= text_area 'email', 'message'  %></p>

<!--[eoform:email]-->

I want to pass from the form a variable @message to email_list in the 
controller, which passes to the MailList model:

class MailList < ActionMailer::Base
	def send_email(email)
		@recipients = email.address
		@from = 'info@toropaintballs.com'
		@subject = 'Toro Paintball'
		@body['full_name'] = email.fullname
                ## @message in here someway ##
	end
end

which invokes the view send_email.rhtml:

Dear <%= @full_name %>,

<%= @message %>

Hope this isn't way too long winded, but is this completely simple to do 
without having to store @message as a session variable or in the DB? 
Can I just take the value of the textarea, pass it through the 
controllers and model to the view like this?
