Most sites dont put email addresses on anymore but use contact forms.
There are good reasons for this, people dont take the email address and fill the inbox with crap, the query/mail can be dircted to the right department and the main one, which is why i dont include my address on my sites is harvester bots. Bots that trawl the web and grab any email addresses they find. Also i dont thik the ceo of the worlds largest company wants his email address public!!
