How can one claim ownership of a Nabble mirrored mailing list?
Our organisation receives frequently messages via the Nabble mirror on our mailing lists. They are often poorly formatted HTML and we would like to either stop some annoyances or stop Nabble altogether to function as a sender conduit. It seem sthat the mailing list mirror was established by someone who no one knows. What do we need to do to be able to administer the mirror and its settings?
