Linux.org appears to be down. The "Linux.org Bot" sent out the below email to Linux.org members.
Hello everyone, linux.org is under new management. Currently linux.org is down for maintenance so if you want to talk Linux checkout the new forum LinuxForum.com Rob setup. Its currently under development but you can join if you wish.
