Does this viewer still viable?
I would like to know too!
I've never used nor SL nor a copybot before, so I can't give you much guidance.
However, I use HydraStorm and haven't had a problem with it. I downloaded the viewer 8 days ago, so I'm pretty sure it's still available
Darkstorm is dead KingGoon no longer does viewers. Your best viewer out now is Hydrastorm.
