I have tried to put links to http://www.dataaccess.com/promos/201...sed_email.html but seems that certain Linkedin's forums ( not all ) take this as a "promo" inmediatly and apart the link to a separate place. Maybe the "promo" word in the path ?

HTML5, Java, WEB designers... are only a few places where are a lot of developers fighting to make what you offer easily.
