I have not tried yet. The Admins posted some instructions, mostly for moderators and Admins, but you have to edit hosts, and it is best to run on a separate system. I am currently only on my laptop, so do not have any extra installs. I just installed 12.04.2 to a flash drive and hope to get it working before conversion.
This is what was posted. If you have further issues ask one of the Admins.
To access the staging forum you will need to edit your hosts file - adding
18.104.22.168 forums.ubuntu.com ubuntuforums.org
You can't run both at the same time, some staff members have dealt with this by using a vm specifically with that in /etc/hosts
There are some threads in FFH which you can add things to,
one is for your thoughts - http://ubuntuforums.org/showthread.php?t=2084290
