Probably to late, but on the page "10 Tips to Quickly Discover Stadda and eZ Publish 5":

1. The title is a bit to long, the short name for menu labels could be simply "Discover eZ Publish 5"

2.
"Stadda is a mountain in the municipality of Tysfjord in Nordland county, Norway. It is located about 15 kilometres (9.3 mi) northeast of the village of Kjøpsvik. The mountain has very smooth sides reaching all the way to the fjord. Stadda has an obelisk-shape which gives it a very distinct look. In 2002, it was voted to be the "National Mountain" of Norway by listeners of NRK. Setind is also the codename for the eZ Publish 5.1 release."

Stetind in mentioned in the end.

I would rather write it:

"Stadda (Lule Sami: Stádda, Norwegian: Stetind or Stetinden) is a mountain in the municipality of Tysfjord in Nordland county, Norway. It is located about 15 kilometres (9.3 mi) northeast of the village of Kjøpsvik. The mountain has very smooth sides reaching all the way to the fjord. Stadda has an obelisk-shape which gives it a very distinct look. In 2002, it was voted to be the "National Mountain" of Norway by listeners of NRK. Stadda is also the codename for the eZ Publish 5.1 release."

Should also add a header (h4/h3) with title "White papers".

3. On page "About": This is not a about page but a contact form, title should reflect that with "Contact us"
