Thread:Support/About OpenImages:Users.delete node sure/ksh

What is meant by "node" and "nodes" in this message? In this message, there is the only occurrance of these terms in the entire project. A generic translation of "node", such as a node in a mesh or network, does not make sense here. It has to be more specific. or closer to the user experience, such as "topic", or "image group", etc., if a node represents something like these. Thank you!
