RadioBoard is back. Or maybe it never went.

Not exactly back
http://r1rl8.skipdns.link/rb/viewtopic.php?f=1&t=9953in short, the domain name registration expired, so the DNS settings were changed to point to a "parking" page, the server hosting the board is still alive and carries all the stuff, but accessing the forum through the domain name doesn't work, the "skipdns" alias has been set up by one of the TRB members, but there's no info about if and when the domain could be renewed and reconfigured to point to the forum
[edit]
A trick to temporarily solve the issue w/o using the "skipdns" link is to add the IP address of TRB to the "hosts" file, in Linux/Unix the file is usually "/etc/hosts" while in windows it is "%SYSTEMROOT%\System32\drivers\etc\hosts", to open/modify it you will need to be to elevate your privileges (sudo or run as admin) and, in windows, to remove the readonly attribute from the file, done that just open it with an editor enter the following to the bottom of the hosts file
162.215.249.87 theradioboard.com
and save the file, that way a direct link like (e.g.)
http://theradioboard.com/rb/ will work, again, it's just a temporary workaround, not a solution; the latter should be carried on by the folks running TRB
