A newsgroup I want to access isn’t available on my server.
Click Reset List in the Newsgroup Subscriptions window. The newsgroup may be new and simply not shown in your current list. If the group still isn’t there, try contacting the ISP or other service that hosts the list and ask that service to add it. Often new groups simply go unnoticed because so many of them are out there. Many news servers are willing to respond to such a request, unless they have a rule restricting or censoring the particular group.
