I know I'm bumping an old thread, but I use three different newznab servers, none of which are currently supported by alt.binz.
It would great if you could not only add generic newznab support, but for multiple different servers. They all have basically the same API functionality and I'm sure it's not much different from your omgwtfnzbs module.
It would be extremely handy to do this, as I am struggling trying to get the RSS feeds to work - though I probably should read the notes on RSS feeds and see what I am doing wrong with the filter and auto accepting into pause.
Thanks
