adlink bought doubleclick's European network of sites a couple of years ago, but still uses their DART system for serving the campaigns. This left doubleclick to sell the DART package directly to publishers/advertisers as an independent solution.
You can join adlink at
http://www.adlink.net/. Think they've got a good range of campaigns - if anyone has tried out Response Republic, that was adlink's cpc network, which had some good brands on board.
If you get turned down by adlink, apply to Response Republic (
http://www.responserepublic.net/en ) and then they might be able to get you a few CPM campaigns going from the parent company when you get settled down.
Hope this helps!
