I've been trying to add WCG to a new laptop and it is failing to add the project in Boinc. I went to the WCG Web site and seems that it has lost access to its backend database which is preventing login or accessing their forums and contact us page.

Is there some way to get in contact with them to let them know things are down? My other Boinc instances continue to work.

Of course the WCG team knows that it's down, and are working on it. Check their Facebook page: https://www.facebook.com/worldcommunitygrid.org

Also check this thread, on this forum, from this post and forward: https://boinc.berkeley.edu/forum_thread.php?id=10279&postid=111141#111141
