Function and position of Search field
Two suggestions about the Search field:
1) The option to search within the product KB ( e.g. Silk Central) vs Search everything should be selected up front, not hidden in a dropdown. Also, the chosen search scope should persist within that session, not default to 'Search Everything' each time. The feature often does not work for me anyway. Even if I select to search Silk Cenrtral I can get responses for Star Team, Silk Performer, etc.
2) Put the Search field closer to the center of the page where the user selects what is being searched (User Forum vs Wiki, etc). Currently the search field is too is far away and in a different frame from the body of the page. I always felt it was out of place.
