21. Good Practices to Follow
AllStar Link AllStarLink.org
Always know what your node is or is not linked to before connecting to another node
Never link two large systems together
When linking your node to a large system it is best to link to a HUB instead of a connected node
HUB nodes generally have a superior Internet connection and handle higher throughput
Administrators can readily troubleshoot and remedy any problems that may arise from a central point
Never daisy-chain nodes to a HUB
Never RF Link to a repeater you do not own without the owner's permission
