Give it a shot

Because I'm bored and like puzzles, decode this to see exactly who the previous post was referring to. I could just tell you but this is more fun. Some people see a puzzle like this and just try and solve the damn thing for the sake of solving it, which I hope is the case because I really doubt anybody cares what the solution is.

Decoding it is not hard. Figuring out what you're looking at is the hard part. Maybe Ethan can figure it out? There is more than one step.
