p.s.
If I may suggest something:
1) disable PDF icon - google sometimes index'ed it and for Google it means clone of article, and normal people do not use it.
2) disable Email icon - spammers robots uses it to send stupid links , I had a client who has got 20 emails per day because of this with super blue pills or If you want to have longer, Free tickets to .... offers. "Normal" people uses FB to spread info, not forms.
