This is the indexer I use. I do not know if the information on the site linked is accurate or not, as I have paid for a lifetime subscription years ago.
I do not know of any USENET servers that offer lifetime subscriptions.
Agreed. Automation is optional. You can easily get started with many popular Windows apps that are readily available (my advice is to always go open-source).
Setting up automation was a laborious task for me. I set it all up on TrueNAS - so it was a bit harder that just using Windows apps and file systems. But, well worth the time!
My indexer has been darn rock solid for all the things I have ever looked for. Do you have any insight as to any other indexer that might benefit me? Got an invite to give out?
