I have scowered there pages for contact Info and cant find anything but an empty IRC channel.....
That's strange.. We're currently 92 people in the channel (#sigrok) and most people stay connected all day long.
Were you able to contact them? I posted this forum topic on their IRC channel.
Are you new to IRC?
It's better if you use an IRC client, there are tons of them for each platform. You can even use multi-procol ones if used to IM, like Miranda and Pidgin.
Please connect to irc.freenode.net and not other network.
Anyway, you could just put #sigrok on the channel text box on the following URL and start chatting
