[BNM] Holding page missing email link CSS/IE mystery

[Yan_fit-pixels]

Would any CSS/html experts possibly care to have a look at this page:
http://www.fit-pixels.com/artist_tickets/artist_ticket1.htm

And see if they could say why the email link 'contact us' is invisible 
in IE 7+6 but appears fine in FF and safri.
It's just underneath the masthead logo to the right - you can even 
select and invoke with but not see the darn thing.

Ps. I've only done the css because we had to do this quickly, the actual 
site will be done by proper people.

Cheers
