This is awkward... When newzbin shut down, I was without a NZB provider for a week. Then 2 days ago I paid for my membership at NZBMatrix. And now it's gone?
Similar position.. but I was waiting a week or two before committing to actual money :)
Glad I did.
Going a bit old school at the mo, downloading headers from a.b.mm for example. Get some retention up myself, might take a while!
