To add to what Cory said, The goal is not to remove control or access from the user. It's simply for network management. It's very much an experimental network, so if you choose not to allow admin accounts on your modem, the network may change and you will be responsible for maintaining it yourself. I'd also like to bring up a parallel with other commercial ISPs. You end up in the same situation. For example, with comcast, you can either rent a modem from them, which they have full admin control of, and may not give you any access at all, or you buy a modem yourself, and configure it to work with them, and any issues or changes are your own responsibility. For us the problem is far more significant. The HamWAN network is changing and evolving all the time, unlike a network like comcast's which is relatively stable. The methods of connecting / authenticating to the network will change, and you should be prepared for that if you decide that allowing a few trusted users on your modem is an unacceptable risk, despite these users having full administrative access to ALL of the rest of the HamWAN network routing your packets. In any case, as Cory said, it is your choice, but the recommended one is what's documented on the wiki instructions. Nigel K7NVH
