Can't hide that welcome message.
You can unpin this message by clicking on the "x" at the upper right hand corner of the box, and this message will never appear again!
There is no X!
What browser are you using? What computer or machine are you using?
Sorry.I am using IE 11.
EDIT: Search field is missing too.
Are you using a tablet or a PC? I can honestly say we haven't tested in ieyet. But we can give it a shot.
I am using laptop with Win 7.

Sorry about this. I tried it with the older Internet Explorer and yeah, you can't see the x. You might try using Microsoft Edge, the new version of Explorer (I can see it there) or using Chrome or Firefox. Or updating IE!
