SAP NetWeaver Portal 7.0 Features

Hello,

I need some information about features of Portal 7.0. I already read the online documentation and couldn´t find these features listed in there:

- Photo Gallery ( To put a photo gallery in the portal )

- Quiz ( to allow users to answer quiz )

- Advertising ( to display advertising to the users according to their interests )

- Auditorship track ( what was the last page viewed by the user X)

- Calendar ( not integrated to Exchange, but as an iView )

- Comments ( after the published content, like as in a blog )

Can anyone help me?

Thanks in Advance,

Murilo
