NSR morphed to where it is from the DPL that was run at TSE. The style of shooting is not suited to new shooters and quite frankly, can put off other recreational shooters. It is what it is though, and I haven't been involved with NSR so that is all I have to say on that subject.
I'd be supprised to learn that TSE doesn't have a DPL (defensive pistol league) or IDPA type of league night anymore.
The ATHL held a few IDPA matches over the winter in the past - I'd be supprised if they have discontinued those also.
