1) how do I make "#{@message[:participant].commentable.item_title}" linked to polymorphic_url(@message[:participant].item_link, :only_path => false)

i.e. in comment_message html

== #{@message[:originator].name} commented on "#{@message[:participant].commentable.item_title}" at #{@message[:site_title]}:
%a{:href=> polymorphic_url(@message[:participant].item_link, :only_path => false) }= I18n.translate('message.click_respond')

2) also - joel wants this footer added to email notifications (not popup notifications) - where/how would I do that

<p>To turn off these email notifications, update your <a href="edit setting page">Your Boston settings</a>.
