When I click on the reviews on the main page or in search results I got to a review page, which also does have a separate URL:

Example:
first "hot review" (currently) leads to
http://critiquebrainz.musicbrainz.org/review/9cce47ae-cbb8-484a-a6b9-2b51a71a685d

However, this seems to have an "onClick" event, but is not a HTML-link element (<a>).
So when I move the mouse over it I don't see the link in the status bar and I don't have the possibility to copy the link target or similar (without going to the link and copying from the location bar).

"Real" Links are used in the menu. When I move the mouse on "Sign In" I see http://critiquebrainz.musicbrainz.org/login/ in the status bar and I can interact with the link with a right click.
That is how it should be for all links.
