It came to my attention that registered users were using the Google search box to search for content within the site. The problem with it, is that Google does not index the site every day, so recent content might not be indexed.
Registered users can use the in-house search feature here:
You can find the link in the left menu.
Our search feature allows you to limit search to specific content types or specific forums.
In order to avoid confusions, I have disabled the Google Search block for registered users, but left it for anonymous (not logged in) users, because that's the only search function they can use.
