Given the expansion of the PPRuNe acronym, plus the computers topic description :
Anyone with questions about the terribly complex world of computers or the internet should try here. We will also try and help with troubleshooting any technical problems you may have with the forums.
I suspect the intention was not to encourage debate or detailed troubleshooting of the joys of commercial or government networks, something for which there already exist many more suitable forums likely to be visited by a greater number of people versed in the technologies involved than PPRuNe.
Obviously within the realms of reasonable free speech and the mods, there's nothing stopping someone starting up a topic on, say BGP troubleshooting.... but I reckon it'd be a lost cause.
Just a thought....
