I posted this in another thread. The info is worth repeating here:
Someone complained that they had not received any notification after the lottery, either successful or not. I suggested that perhaps he had another Recreation.gov acct that he'd forgotten. Turns out his wife had created a new account to submit a lottery application. He wrote:
I started thinking about it and talked to the wife who applied for me. She opened a new account when she applied for the lottery. I did receive my first choice in July so I can finish what I started.
A different individual contacted me privately, and I suggested the same thing, but that wasn't the case. He called the Wilderness Permit office, and they were able to look at his application and tell him it was unsuccessful. He then went online early on April 1 and reserved a good permit.
Coincidentally, he also reported both he and a friend BOTH received their lottery notices on April 1. Sounds like a glitch exists in the Recreation.gov system.
