First I wanted to mention I am glad to read Bjorn's message about adding some content to the network.
Keeping in contact is key. Be that a coordinator or any host on the amprnet. Seems every few months on here we are discussing how someone is sending out random packets, and a straight forward way to get a hold of people would be helpful.
Some time back it was brought up to have a whois server or something like that. I bet I can guess the status of that.
As for everyone having an ampr.org email address, perhaps a forwarding service like the arrl.net addresses? Then there is the possible spam problem, and the fact that someone would need to set up such a service.
Overall a lot of good ideas are brought up on this list, so few ever happen. The only solution I am offering is everyone should help spread the word and try and get more people involved with moving this network forward. I wish I had better coding skills.
One of the core problems at least in my country where the ampr/44net space is not well utilized is the lack of higher speed equipment to build a network. You really have to be part of a well organized club with site connections to do anything microwave on any big scale from what I have seen.
